Description

Laparoscopic surgical instrument and laparoscopic surgical device

Technical Field

The embodiment of the application relates to a medical instrument, in particular to a laparoscopic surgical instrument and laparoscopic surgical equipment.

Background

Technological advances in laparoscopic surgery have led to new developments in laparoscopic partial nephrectomy. However, the requirement of the operation is high, when the tumor is removed and the wound is sutured, the renal artery needs to be temporarily blocked by using the blood vessel blocking clamp, the bleeding amount is reduced, a clear operation field is provided, and the arterial blood flow is reopened after the operation is finished. This procedure leaves the kidneys in a warm ischemic state, severely affecting renal function, and therefore, tumor resection and suture of the wound must be completed in a limited time. Research finds that the reduction of the kidney temperature can effectively reduce the metabolic rate of the kidney, reduce the negative effects caused by ischemia and provide longer operation time on the basis of protecting the kidney function, so that how to solve the problem of reducing the temperature of the kidney in the operation becomes a key scientific problem to be solved urgently.

In view of the above problems of renal ischemia, chinese patent No. CN201510553456.5 provides a kidney cooling sac for cooling the kidney by the contact of the sac with the surface of the kidney, but the cooling efficiency of this solution is low.

In addition, chinese patent No. CN201010239955.4 provides a renal artery blocking and cold perfusion apparatus, which fixes a renal artery puncture needle on a renal artery blocking clip, and reduces the temperature of the kidney by perfusing a cooling liquid, although the cooling efficiency achieved by the solution is high, however, since the renal artery puncture needle provided by the solution is vertically arranged in the longitudinal direction and horizontally fixed at 60 ° in the middle of the front half of the renal artery blocking clip, the whole circumferential dimension formed by the puncture needle and the blocking clip after integration is large, and the problem that the whole renal artery blocking and cold perfusion apparatus is difficult to enter the Trocar channel is easily caused; in addition, when the blood vessel is pinched, the cross section of the nearby blood vessel is flattened to be in an oval shape, and the puncture needle is vertical in the longitudinal direction and fixed on the renal artery blocking clamp at an angle of 60 degrees horizontally, so that the puncture needle can tend to the minor axis direction of the oval cross section to puncture the pinched blood vessel, the puncture stroke is short, the abnormality of blood vessel puncture is easily caused, and the puncture risk is high, so that a doctor often needs to adjust in the operation process, for example, turn over the blood vessel, to avoid the occurrence of the abnormality, and the problems of inconvenient operation and increased operation difficulty are caused. In addition, since the puncture needle head is a rigid hollow needle, other mechanical injuries are easily caused along with the actuation of the renal artery blocking clamp in the operation.

In view of the above, how to provide a laparoscopic surgical instrument to overcome the various problems existing in the prior art is the technical problem to be solved by the present application.
