Fig. 2 is a schematic structural view of the incision retractor fixator of the present invention.

Figure 3 is a top view of the incision retraction holder.

Wherein: 1. the incision retractor comprises an incision retracting fixator, 2 parts of gloves, 3 parts of a laparoscope puncture cannula, 4 parts of a supporting snap ring, 5 parts of an incision retracting pipeline, 6 parts of a connecting snap ring, 7 parts of a flange.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in figure 1, the single-port laparoscope access channel comprises a glove, wherein the tail end of at least one finger sleeve of the glove is transversely provided with a through hole, and a laparoscope puncture cannula is hermetically connected to the through hole. An incision retracting fixer is connected to the opening of the wrist of the glove in a sealing manner, and the laparoscope puncture sleeve, the glove and the incision retracting fixer are sequentially communicated to form a single-port laparoscope access channel. The pipe orifice of the laparoscope puncture cannula extends into the glove through the through hole, and the instrument enters the single-hole laparoscope access channel through the laparoscope puncture cannula, and finally reaches the incision for operation. The side wall of the laparoscope puncture cannula is provided with a pneumoperitoneum tube connecting port and a valve. The through holes of the finger sleeves of the glove are mutually independent, so that the single-hole access channel is equivalent to a single-hole laparoscope access channel with a plurality of mutually independent inlets and a multi-cavity channel.

Sterile rubber gloves are adopted as the gloves, and the operation swing range among all instruments is not limited, thereby being beneficial to the normal operation of the operation.

As shown in fig. 2 and 3, the incision retracting fixator is integrally i-shaped and adopts an integrally molded structure. Including the incision lead out the pipeline, strut the snap ring and connect the snap ring, the incision leads out pipeline and gloves intercommunication, struts the snap ring setting and leads out the pipeline lower extreme at the incision for strut the incision, and then make incision and incision lead out the pipeline outer wall and closely laminate, connect the snap ring and be used for connecting the gloves wrist, make the incision lead out the fixer and be connected fixedly with the gloves wrist. The inner edges of the support snap ring and the connection snap ring are smoothly connected with the outer edge of the incision retraction channel, and the opposite directions of the outer edge and the connection snap ring are raised to form flanges. The flange of the supporting snap ring is used for clamping the incision, so that the incision retraction fixator is prevented from being separated from the incision in the operation process. The flanges on the connecting snap rings facilitate the silk thread to be sewn on the wrist of the glove in a pouch shape. The diameter of the opening channel before the incision is 3.5cm, and the diameter of the outer ring for opening the clamping ring and connecting the clamping ring is 7 cm.

The incision retractor fixator is prepared from a thermoplastic elastic body material, has good plasticity and elasticity, is different from rubber gloves, and the rubber gloves have certain elasticity and plasticity but cannot be restored to an initial state after deformation and need to be inflated through pneumoperitoneum tubes to stretch the gloves. The incision retracting pipeline of the incision retracting fixator can always keep smooth without other additional operations. The expansion clamp ring can be extruded and folded before entering the incision, so that the incision can be rapidly entered, and meanwhile, the initial structure can be rapidly recovered after the incision is entered, the incision is clamped, and the establishment of the access channel of the single-port laparoscope is rapid and convenient.

The incision retracting pipeline of the incision retracting fixator is also internally provided with a partition plate which partitions the incision retracting pipeline. Although the instruments are arranged in the access channel of the single-port laparoscope through different finger sleeves, collision and interference among the instruments are avoided to a certain extent, due to the limitation of the size and the structure of the incision retraction pipeline, the incision retraction pipeline is directly connected with the incision, the tail ends of the surgical instruments may collide and interfere in the incision retraction fixator, and the partition plate can thoroughly avoid the phenomenon. The spacing plate is arranged in the incision retracting pipeline and is vertical to the incision retracting pipeline, and the two can adopt a separable mode or an integrated molding structure. The material of the partition board is the same as that of the incision retracting fixator, a plurality of mutually independent partition holes are formed in the partition board, the number of the partition holes is at most five, and the partition holes correspond to the maximum number of glove finger sleeves. When the instrument passes through the incision retractor fixator, the instrument can pass through different spacing holes and then enter the incision operation position, so that collision cannot occur, and the normal operation of the instrument in the operation process cannot be influenced.

When a patient is subjected to laparoscopic surgery, the umbilical fossa is cleaned before the surgery and local skin preparation is carried out, after general anesthesia, a sterile surgical towel is laid in a conventional disinfection mode, a longitudinal incision with the length of about 3.0cm is made to penetrate through the navel, the skin and subcutaneous tissues are incised layer by layer into the abdomen, and the visceral organs in the abdominal cavity are prevented from being damaged in the operation.

The establishment process of the access channel of the single-port laparoscope comprises the following steps:

annularly sewing the wrist part of the glove 1.5cm away from the edge by using a fourth silk thread for a circle to form a purse shape;

then, cutting the finger sleeves of the thumb, the middle finger and the little finger of the glove by using scissors, wherein the diameters of through holes at the tail ends of the thumb and the little finger are 0.5cm, the diameter of the through hole at the tail end of the middle finger sleeve is 1cm, and a laparoscope puncture tube sleeve is placed in each through hole and is ligated and fixed by using silk threads;

placing an incision opening snap ring of the incision retracting fixator into an incision, penetrating a finger through the incision retracting fixator, and checking whether the incision is in sealing fit with the outer wall of the incision retracting channel;

then the connecting snap ring of the incision retracting fixator is sleeved into the pouch shape of the wrist part of the glove, and the silk thread on the pouch shape is pulled to tighten the pouch to seal the incision retracting fixator and the glove;

and finally, connecting a ventilation abdominal tube, opening a valve on the laparoscope puncture tube sleeve, setting the pneumoperitoneum pressure to be 13 mmHg, and enabling instruments needed in the operation process to enter the single-hole laparoscope access channel through the laparoscope puncture tube sleeve.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
