Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an access device for single-port laparoscopic surgery. Background Art

[0002] With the development of surgery, we have entered the era of minimally invasive surgery. Single-port laparoscopic surgery (LESS) is developed from laparoscopic surgery. Since only a single channel is needed to enter the pelvic and abdominal cavity, it causes less trauma to the body surface than general laparoscopic surgery. LESS mostly uses the natural scar of the human umbilicus for surgery. No other scars will be left on the abdominal wall except the umbilicus. Single-port laparoscopic technology uses a separate incision in the umbilicus, and the suture is done within the fascia to hide or reduce the scar and maintain the integrity of the abdominal wall. Conventional laparoscopic surgery requires 3 or 4 puncture holes, and a small scar will be left on the surface of the abdominal wall. Therefore, single-port laparoscopy is the most feasible "scarless" technology at this stage and is more easily accepted by female patients.

[0003] During single-port laparoscopic surgery, since multiple laparoscopic surgical instruments enter the abdominal cavity through a single-port channel for surgical operations, it is easy for the instruments to collide with each other, which is not conducive to subsequent surgical operations. For this reason, most existing single-port laparoscope-specific access devices are used for auxiliary surgery. However, the existing domestic conventional laparoscopic trocar kit costs 1,500 yuan, and the domestic special port generally costs 2,000 to 4,000 yuan. The cost of imported trocars or ports is even higher, and the cost of incision protection covers is also 700 yuan, resulting in high costs. In addition, the subsequent cleaning and maintenance are very inconvenient, which is not conducive to the promotion and use of primary hospitals. Utility Model Content

[0004] In order to overcome the deficiencies in the background technology, the utility model discloses an access device for single-port laparoscopic surgery. The utility model improves medical gloves so that the instruments required for laparoscopic surgery can be inserted into the abdominal cavity from independent access mechanisms, which not only effectively avoids interference between the various instruments, but also provides great convenience for subsequent laparoscopic surgical operations.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0028] Please refer to the instruction manual Figure 1-4 , the utility model provides a technical solution:

[0029] Embodiment 1, a single-port laparoscopic surgical access device, comprising a medical glove 3, wherein the upper portion of the medical glove 3 is provided with at least one through hole 2 formed by truncating the end of the finger sleeve, wherein an access mechanism 1 for inserting and installing laparoscopic surgical instruments can be detachably installed in the through hole 2, wherein the access mechanism 1 comprises a sleeve 13 having an open structure at both ends and embedded in the through hole 2, wherein the sleeve 13 is in interference sealing cooperation with the through hole 2, and in order to ensure that the sealing connection between the sleeve 13 and the through hole 2 is effective, the sleeve 13 The lower part of the outer wall is an outwardly inclined expansion slope 15, and the expansion slope 15 can make the lower part of the outer wall of the sleeve 13 contact the inner wall of the through hole 2 more tightly and firmly. The outer wall of the sleeve 13 is provided with an annular groove 10, and a rubber ring 11 is detachably installed in the annular groove 10. The sleeve 13 is inserted into the through hole 2 at the end of the finger sleeve through the opening at the lower part of the medical glove 3. The finger sleeve covers the outer wall of the sleeve 13, and the rubber ring 11 is snapped into the annular groove 10 to achieve a fixed seal between the sleeve 13 and the through hole 2;

[0030] An annular step 17 is provided at the lower end of the inner cavity of the sleeve 13, and a rubber block 14 with an interference fit with the inner wall of the sleeve 13 is clamped on the upper part of the annular step 17. A through hole 16 that penetrates the rubber block 14 in the middle and is automatically closed by elastic force, and a fixing mechanism connected to the laparoscopic incision and used for expanding the laparoscopic incision is detachably installed in the lower opening of the medical glove 3. The fixing mechanism includes an upper limiting ring 4 embedded in the opening of the medical glove 3 and located outside the abdominal incision, and an upper limiting ring 4 embedded in the opening of the medical glove 3 and located outside the abdominal incision. The lower limiting ring 6 inside the abdominal incision, the upper limiting ring 4 and the lower limiting ring 6 are all made of PVC suction tube. When the lower limiting ring 6 is inserted into the abdominal incision, it can be inserted from the abdominal incision by applying force to bend the lower limiting ring 6. After insertion, the lower limiting ring 6 automatically resets and is blocked on the inner wall of the abdominal cavity. In order to ensure that the upper limiting ring 4 and the lower limiting ring 6 are firmly and stably installed with the medical gloves 3, several clamping rings 5 ​​that are clamped with the upper limiting ring 4 and the lower limiting ring 6 inside the medical gloves 3 are also provided on the outside of the medical gloves 3.

[0031] In the second embodiment, in order to prevent the expansion gas from leaking out from the insertion hole 16, a sealing block 8 with an interference fit with the expansion hole 9 is detachably installed in the expansion hole 9, and a rotating handle 7 is provided on the upper end of the sealing block 8. Since the insertion hole 16 is usually in a closed state and is not easy to see, in order to enable medical personnel to quickly and accurately insert abdominal instruments into the insertion hole 16, the inner cavity of the sleeve 13 on the upper part of the rubber block 14 forms an expansion hole 9 with an inverted cone structure, and the upper surface of the rubber block 14 is provided with a guide groove 12 with an inverted cone structure. The insertion hole 16 is arranged in the middle of the inner bottom surface of the guide groove 12. Through the guidance of the expansion hole 9 and the guide groove 12, the abdominal instrument can be quickly and accurately calibrated with the insertion hole 16, which provides convenience for subsequent insertion.

[0032] Embodiment three, when the upper limiting ring 4 and the lower limiting ring 6 are installed, the upper limiting ring 4 and the lower limiting ring 6 only rely on their expansion to fit with the medical gloves 3. In order to increase the friction between the upper limiting ring 4 and the lower limiting ring 6 and the medical gloves 3, the tube bodies of the upper limiting ring 4 and the lower limiting ring 6 are provided with a plurality of limiting edges 18 arranged in an orderly manner at intervals. During the installation and use process, it is necessary to apply force to the upper limiting ring 4 and the lower limiting ring 6, which can easily cause the upper limiting ring 4 and the lower limiting ring 6 to be displaced. In order to ensure that the upper limiting ring 4 and the lower limiting ring 6 are firmly and stably connected to the medical gloves 3, the inner surface of the clamping ring 5 is provided with a convex edge 19 that is compatible with the limiting edges 18 on the upper limiting ring 4 and the lower limiting ring 6.
