Description

Incision protective sleeve for endoscopic surgery

Technical Field

The utility model belongs to the appliance for the laparoscopic surgery especially relates to an laparoscopic surgery incision protective sheath.

Background

Endoscopic surgery makes it possible to perform the operation through a small incision, which is less destructive to the tissues than conventional surgical operations, through which a small light source, a camera and surgical instruments are inserted, and the surgeon guides the operation of the surgical instruments through the images transmitted to the monitor, with the characteristics of less trauma, less complications, safety and quick recovery. In the operation process, need use an incision protective sheath, fix a position in incision department and strut the incision for operation relevant operation apparatus can get into the interior operation of human body chamber through the incision protective sheath, reduces the injury of operation apparatus to human tissue. However, in the current single-hole thoracoscopic surgery, all operating instruments enter and exit from an incision, namely an operating hole of an incision protective sleeve, the endoscope is easy to interfere with other operating instruments, the operation is affected, the endoscope cannot be stably supported, and is required to be held by hands all the time, so that the problems of fatigue of holding the endoscope and lens shaking are easily caused. In order to solve the problem, chinese utility model patent document No. CN208598452U discloses an incision retracting fixator for endoscope, which comprises an outer ring, an inserting ring and a flexible channel, wherein an endoscope channel tube fixedly connected with an inner wall is arranged in the inner cavity of the flexible channel. Although the endoscope can pass through the built-in endoscope channel tube to be used for assisting in fixing the endoscope, the endoscope channel tube is positioned in the flexible channel and cannot be too large, so that the diameter of the endoscope channel tube is smaller, the endoscope channel tube has a certain length, the narrow channel enables the endoscope to have large friction with the endoscope channel tube, the endoscope cannot conveniently stretch into and withdraw from the narrow channel, and the endoscope cannot conveniently incline towards the peripheral side to adjust the angle, so that the endoscope can advance and withdraw inwards or horizontally and the angle adjustment in the horizontal direction is limited; in addition, because the incision of laparoscopic surgery is all smaller, this kind of built-in endoscope passageway pipe has taken up the finite space of operation hole passageway for this is narrower and smaller operation passageway, does not thoroughly solve the problem that endoscope and operation apparatus take place the interference, has influenced operation apparatus's operation, and the operation of operation is inconvenient, and the degree of difficulty increases.

Detailed Description

The preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

Example 1: referring to fig. 1 and 2, an laparoscopic surgery incision protective sheath, including two solid fixed rings 1 and connect two gu fixed ring 1's flexible line 2, flexible line 2 includes tubaeform 21 and passageway pipe 22, two solid fixed rings 1 are connected with passageway pipe 22 through tubaeform 21, and the diameter of passageway pipe 22 is less than the diameter of two solid fixed rings 1, and in this embodiment, two solid fixed rings 1 are oval-shaped ring, and oval-shaped solid fixed ring 1 more adapts to human intercostal structure, and the incision more adaptation laminating between the rib. The two fixing rings 1 are different in size, and when the fixing ring is used, the small fixing ring 1 is positioned on the inner side of the thoracic cavity, and the large fixing ring 1 is positioned on the outer side of the thoracic cavity.

In two solid fixed rings 1, wherein be provided with flexible belt 3 on great solid fixed ring 1, the same half side at solid fixed ring 1 is connected at the both ends of flexible belt 3, and the both ends of flexible belt 3 are close to solid fixed ring 1's edge, are equipped with two round pins 4 on solid fixed ring 1, the both ends of flexible belt 3 respectively with solid fixed ring 1 on round pin 4 rotationally connects. The flexible band 3 forms a half loop and can swing around the connection point of its two ends, the middle of the flexible band 3 forming a positioning ring through the endoscope when the flexible band 3 turns in the axial direction of the flexible tube 2. The flexible belt 3 forms a semi-ring, the endoscope is sleeved fixedly by the semi-ring positioned on the outer side of the flexible pipeline 2, so that the function of auxiliary fixation is achieved, and the fatigue of the endoscope is reduced; because the semi-ring is positioned outside the flexible pipeline 2, the semi-ring can be arranged to be larger, and the flexible belt 3 is narrower, so that the contact area with the endoscope is small, the endoscope can conveniently and freely move no matter the endoscope stretches inwards and outwards, or swings forwards, backwards, leftwards and rightwards, and the movable range is large; and an endoscope channel with a wall thickness is not required to be arranged in the flexible pipeline 2, so that the interference of the endoscope and a surgical instrument is reduced, and the operation is convenient. The material of the fixed ring 1, the flexible pipeline 2 and the flexible belt 3 is polyurethane or silica gel.

As shown in fig. 2, in the present technical solution, the flexible band 3 forms a semi-ring which can swing, when not in use, the flexible band 3 can be turned to the outside far away from the flexible pipe 2, as shown in fig. 1, when in use, the flexible band is turned to the inside facing the flexible pipe 2, which is convenient to use.

As shown in FIG. 3, the flexible band 3 is provided with 2-3 holes 31 at both ends thereof, and each hole 31 has slits 32 at both ends thereof. The size of the semi-ring formed by the flexible belt 3 can be adjusted by selecting holes 31 at different positions to be connected with the pin 4, the pin 4 is provided with a ring groove, and the flexible belt 3 is provided with the holes 31 matched with the ring groove. The hole 31 of the flexible band 3 is placed in the ring groove so that the flexible band 3 does not come off the pin 4, and the slits 32 at both ends of the hole 31 allow the hole 31 to be enlarged to penetrate from the end of the pin 4 into the ring groove when the flexible band 3 is assembled with the pin 4.

Example 2: as shown in fig. 4 and 5, the present embodiment includes components, the structure of the components, and the interrelation between the components, which are substantially the same as those of embodiment 1, except that two fixing rings 1 are circular and have the same diameter, the end of a pin 4 disposed on one fixing ring 1 is a semicircular head, a hole 31 adapted to the diameter of the rod portion of the pin 4 is disposed on the flexible belt 3, and both ends of the hole 31 are provided with slits 32. The flexible belt 3 is prevented from being separated from the pin 4 by the semicircular head, and the slits 32 at the two ends of the hole 31 are also used for assembling the flexible belt 3 and the pin 4, after the assembling is finished, the slits 32 are closed, and the diameter of the hole 31 returns to the normal state.

The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
