Abstract
Description
- The present application is a continuation of and claims the benefit of the filing date of U.S. patent application Ser. No. 09/994,321, filed on Nov. 26, 2001, entitled, “TROCAR.”
- 1. Field of the Invention
- The present invention relates to surgical instruments known as trocars which are used in endoscopic surgery to pierce or puncture an anatomical cavity of a patient to provide communication with the cavity during a surgical procedure. More particularly, the present invention relates to an improved non-cutting piercing tip of an obturator assembly of a trocar.
- 2. Description of the Prior Art
- Endoscopic surgery is a significant method of performing surgical operations and has become the surgical procedure of choice due to its patient care advantages over “open surgery.” A particular type of endoscopic surgery is laparoscopic surgery. A significant advantage of laparoscopic surgery over open surgery is the decreased post-operative recovery time. In most instances, a patient is able to leave the hospital within hours after laparoscopic surgery has been performed, whereas with open surgery, a patient requires several days of hospital care to recover. Additionally, laparoscopic surgery achieves decreased incidents of post-operative abdominal adhesions, decreased post-operative pain, and enhanced cosmetic results.
- Conventionally, a laparoscopic surgical procedure begins with the insufflation of the abdominal cavity with carbon dioxide. The introduction of this gas into the abdominal cavity lifts the abdominal wall away from the internal viscera. The abdominal wall is then pierced or penetrated with a device known as a trocar. A trocar includes a housing assembly, a cannula assembly attached to the housing assembly to form a bore through the trocar, and a piercing element called an obturator. The obturator slides through an access port formed on the upper end of the housing assembly and through the bore of the trocar. After insertion of the trocar through the abdominal wall of the patient, the obturator is removed by the surgeon while leaving the cannula protruding through the abdominal wall. Laparoscopic instruments can then be inserted through the cannula to view internal organs and to perform surgical procedures.
- Traditionally, the piercing tip of the obturator of a trocar has employed a sharp cutting blade to assist the surgeon in penetrating the abdominal wall. However, certain trocars, for example, as disclosed in U.S. Pat. No. 5,817,601 to Goodwin, have employed a pair of blunt-edged blades or tissue separators which are located on the tip of the trocar to facilitate the penetration or dissection of tissue.
- Both of the trocar assemblies disclosed in U.S. Pat. No. 5,817,061 to Goodwin and U.S. Pat. No. 5,591,192 to Privitera are manufactured and sold by Ethicon Endo-Surgery, Inc. Trocars as described in the '061 and '192 patents have at the time of filing this application been recalled by Ethicon since the tip of the obturator has been prone to failure. In particular, the tip of the trocars disclosed in the '061 and '192 patents have experienced incidents of snapping off during the insertion of the trocar. It is believed that this failure may be attributable to the blunt shape of the tip and the forces to which the tip is subjected upon insertion.
- Accordingly, it would be desirable to have an obturator of a trocar with a blunt piercing tip that is structurally capable of resisting increased insertion forces associated with blunt tipped obturators without failing. This novel and useful result has been achieved by the present invention.
- In accordance with the present invention, a trocar is provided which comprises a metal housing assembly and a cannula assembly attached to the housing assembly to define an axial bore therethrough.
- A trocar in accordance with the present invention may further comprise an obturator assembly which slidably engages the axial bore defined by the cannula assembly. The obturator assembly comprises a shaft having a piercing end for insertion into a patient and a handling end for gripping by a surgeon. The piercing end of the shaft of the obturator includes a piercing tip having an upper face and a lower face which taper from the shaft to form a non-conical, blunt head. Additionally, wing elements having a conical-shaped point and beveled lateral edges are located on opposite sides of the piercing tip between the upper face and lower face.
- In a preferred embodiment of the present invention, the piercing tip of the obturator is removably attached to the shaft of the obturator. Therefore, the obturator may be used with piercing tips of various configurations-such as blunt tips to separate tissue and sharp tips for cutting tissue.
- In accordance with the present invention, penetration forces associated with insertion of a blunt tip trocar into a wound track of a patient are reduced due to the improved wing elements. The conical point and beveled lateral edges of each wing element widen the wound track to ease insertion of the trocar into the patient. As a result, a trocar in accordance with the present invention is better able to resist these penetration forces without failure as compared to existing blunt tip trocars.
- In the accompanying drawings:
-
FIG. 1 is an exploded perspective view of an embodiment of a trocar in accordance with the present invention. -
FIG. 2A is an enlarged perspective view of a piercing tip of an obturator in accordance with the present invention. - With reference to
FIG. 1 , a trocar 5 in accordance with the present invention comprises ahousing assembly 10 to which is attached acannula assembly 20. Thecannula assembly 20 is a hollow tube, and when attached to thehousing assembly 10, a bore is defined through the trocar 5. - Still with reference to
FIG. 1 , a trocar 5 in accordance with the present invention also includes an obturator assembly 30 having ashaft 31 with ahandling end 32 and apiercing end 33. An arcuate-shaped cap 34 is attached to thehandling end 32 of theshaft 31 to facilitate insertion and maneuvering of the obturator assembly 30 by a surgeon. Aremovable piercing tip 35 is attached to thepiercing end 33 of theshaft 31. The obturator assembly 30 slides in the bore that is defined by the combination ofhousing assembly 10 andcannula assembly 20. - While the
shaft 31 of the obturator assembly 30 is preferably formed from a stainless steel material, those skilled in the art will appreciate that the obturator shaft may be formed from a variety of suitable materials. - With reference to
FIG. 2 , thepiercing tip 35 of the obturator assembly 30 is shown in more detail. Thepiercing tip 35 comprises abody 36 having anupper face 36A and alower face 36B. Theupper face 36A andlower face 36B taper away from theshaft 31. Thebody 36 of thepiercing tip 35 partially houses aninsert blade 37. Theinsert blade 37 comprises a blunt,non-conical head 38 and two wing elements 39A, 39B which protrude outward from thebody 36 of thepiercing tip 35. Each of the wing elements 39A, 39B has aconical point 40A and beveledlateral edges 40B. The wing elements 39A, 39B are located between theupper face 36A andlower face 36B of thebody 36 and are spaced approximately 180 degrees apart. Theinsert blade 37 may be fabricated from metal or a hard plastic material. - While a preferred embodiment of the present invention includes an
insert blade 37 protruding from abody 36 of a piercingtip 35, it is intended that the insert blade and the body of the piercing tip can be fabricated as a monolithic piece from metal or hard plastic. - With respect to
FIGS. 1 and 2 , in accordance with the present invention, the piercingtip 35 of the obturator assembly 30 is preferably removably attached to the piercingend 33 of theshaft 31 of the obturator. This removability allows a surgeon to interchange between various piercing tips which are tailored to a particular application—such as sharp piercing tips for cutting tissue or blunt piercing tips for separating tissue. The techniques for making removable tips for trocars is well-known in the art, for example as shown in U.S. Pat. No. 5,697,947 to Wolf, which is incorporated herein by reference. - While the piercing
tip 35 is preferably removably attached to the piercingend 33 of theshaft 31 of the obturator assembly 30, the piercing tip may also be formed on the piercing end of the shaft such that the obturator assembly is a monolithic piece. - With a trocar in accordance with the present invention, it is believed that less force will be required to insert the obturator assembly into a patient than the force required with conventional trocars. Furthermore, the blunt head of the piercing tip-as opposed to a sharp, conical head—prevents internal structures from being cut if encountered during insertion of the obturator assembly. Still furthermore, the design of the tip of the trocar as illustrated in
FIG. 2 , forces the penetration forces to act away from the tip, which eases the penetration of the trocar into the patient. - The foregoing and other advantages of the invention will be apparent to those skilled in the art.
