Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a split laparoscope surgical incision protection device. Background Art

[0002] Laparo-Endoscopic Single-Site Surgery (LESS), sometimes also called Single Incision Laparoscopic Surgery (SILS), is an advanced minimally invasive surgical technique. This surgical method is characterized by the completion of the surgical procedure through a single incision in the patient's umbilicus, rather than multiple incisions as in traditional laparoscopic surgery.

[0003] As a revolutionary development in the field of minimally invasive surgery, single-port laparoscopic surgery (LESS or SILS) has attracted much attention in recent years. This technology cleverly utilizes the natural anatomical orifices of the human body, especially the hidden and natural entrance of the umbilicus, to achieve complex surgical procedures that originally required multiple orifices through only a single orifice. Compared with traditional three-port or four-port laparoscopic surgery, single-port surgery not only significantly improves the degree of minimally invasiveness, but also brings lower postoperative complication rates, faster recovery speed and better cosmetic effects, thereby greatly reducing patients' postoperative pain and recovery time.

[0004] However, despite the many advantages of single-port laparoscopic surgery, it also faces a series of technical and clinical challenges. Among them, one of the most prominent issues is how to effectively protect the fragile skin and soft tissue around the surgical incision. During the operation, the frequent entry and exit of various medical instruments, as well as the resulting friction, squeezing and pulling, increase the risk of mechanical damage and bacterial infection in the incision area. In addition, direct contact between the instrument and the incision may cause tissue edema, inflammation and even incision dehiscence, thereby prolonging the recovery period and increasing the possibility of infection.

[0005] Therefore, it is urgent to develop a split laparoscopic surgical incision protection device to solve the above-mentioned technical problems. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0034] The following is combined with Figure 1 —2 The present application is further described in detail. An embodiment of the present application discloses a split laparoscopic surgical incision protection device.

[0035] Reference Figure 1 and Figure 2As shown, a split laparoscopic surgical incision protection device includes a base 100, a protective cover 200 and an operating table 300. The top of the base 100 is set in a waist shape, and the top of the base 100 is provided with an external thread, and the bottom of the protective cover 200 is provided with an internal thread corresponding thereto. The two are firmly connected by precise matching of the threads, ensuring the sealing and stability of the device as a whole. The operating table 300 is rotatably set on the top of the protective cover 200. A through cavity 130 for the passage of surgical instruments is opened in the center of the base 100, and a cavity 240 interconnected with the through cavity 130 is opened inside the protective cover 200. A channel group for guiding and positioning surgical instruments into the patient's body is provided on the operating table 300.

[0036] In actual application, the base 100 will be directly inserted into the patient's surgical incision, with its bottom abutting against the inner wall of the patient's abdominal cavity and its side walls close to the edge of the incision, forming an effective physical barrier, effectively isolating the direct contact between the surgical instrument and the edge of the incision, significantly reducing the friction, squeezing and pulling of the instrument on the skin and soft tissue, thereby reducing the mechanical damage and infection risk of the tissue around the incision. In order to further improve the patient's comfort and reduce surgical incision irritation, the base 100, protective cover 200 and operating table 300 are preferably made of transparent soft materials, which not only ensures good visual monitoring, but also ensures softness and comfort in contact with the skin.

[0037] During the placement process, the base can be squeezed to deform and put in and out of the surgical incision. After it is placed in the patient's chest cavity or abdominal cavity, the bottom sub-lumbar outer wall of the base just abuts against the inner wall of the patient's chest cavity or abdominal cavity.

[0038] An air ring 110 is fixedly connected to the base 100 and is arranged along the circumferential direction of the base 100. When the base 100 is inserted into the surgical incision of the patient, the air ring 110 is used to fit the edge where the side wall of the base 100 contacts the edge of the incision to form a perfect sealing ring, especially in thoracic or abdominal surgery, which effectively prevents the formation of pneumothorax and ensures that gas does not leak during the operation.

[0039] An inflation valve 120 is provided on the balloon 110, and gas is replenished inside the balloon 110 through the inflation valve 120, so that the balloon 110 is always kept filled during the operation, tightly fitting the edge of the incision to form an efficient seal, especially in thoracic or abdominal surgery, effectively preventing the formation of pneumothorax and ensuring that gas does not leak during the operation.

[0040] In addition, the presence of the inflation valve 120 allows medical staff to dynamically adjust the amount of gas in the balloon 110 according to actual needs to ensure that it forms an optimal fit with the edge of the surgical incision, thereby improving the sealing effect. At the same time, gas can be replenished in time according to the progress of the operation to maintain the filling state of the balloon 110.

[0041] An airbag 210 is disposed in the middle of the protective cover 200, that is, the protective cover 200 is composed of two parts, and the two parts of the protective cover 200 are respectively fixedly connected to the two sides of the airbag 210. The interior of the airbag 210 is communicated with the cavity 240 of the protective cover 200, and the exterior of the airbag 210 is extended outwardly in the radial direction of the protective cover 200. The airbag 210 is provided with an inlet valve 220 for inflating the interior and an outlet valve 230 for exhausting the air to the outside.

[0042] However, when the patient has more skin and fat, the airbag 210 is inflated, and the airbag 210 expands under the support of the gas to adjust the size of the protective cover 200. And when the patient's surgical environment needs to be in a pneumothorax state, the airbag 210 is inflated through the air inlet valve 220, so that carbon dioxide is filled into the patient's interior through the cavity 240 of the protective cover 200 and the cavity 240 of the base 100, so that carbon dioxide can smoothly enter the patient's body through these channels, thereby quickly establishing and maintaining the required pneumothorax state. Its outlet valve 230 can exhaust the gas generated during the operation.

[0043] Among them, the air intake volume of the air intake valve 220 is greater than the air outlet volume of the air outlet valve 230, so that inflation can be performed simultaneously during the exhaust process during the operation to ensure sufficient gas replenishment, thereby maintaining the stability of the pneumothorax state, providing the doctor with a clear surgical field of view, and reducing the surgical risk.

[0044] The air inlet valve 220 and the air outlet valve 230 are symmetrically arranged to reduce the mutual influence during the exhaust and intake processes.

[0045] An annular protrusion 350 is provided on the outer wall of the operating table 300, and an annular groove 340 is provided on the top inner wall of the protective cover 200. The annular protrusion 350 is rotatably arranged in the protective cover 200, so that the operating table 300 can adjust the position and angle of the channel group by rotation during use. Therefore, the rotatable feature of the operating table 300 enables the surgeon to flexibly adjust the angle of the instrument, simplifying the surgical steps and improving the surgical efficiency.

[0046] The top circumferential side wall of the operating table 300 is fixedly connected with a collar 310, which is sleeved on the top of the protective cover 200. In this way, the operating table 300 can be rotated by turning the collar 310 during the operation, so that when performing delicate operations, the doctor can more easily adjust the angle of the instrument to achieve the best surgical field of view and operational convenience. In addition, the design of the collar 310 also ensures a stable connection between the operating table 300 and the protective cover 200, avoiding the displacement of the equipment due to accidental collision during the operation, thereby improving the safety of the operation.

[0047] Reference Figure 1and Figure 2 As shown, the channel group includes an endoscope hole 330 for inserting a thoracoscopic endoscope and a laparoscope operation hole 320 for inserting a laparoscope instrument for operation in the thoracoscopic endoscope. The endoscope hole 330 preferably has a diameter of 10 mm, and at least two laparoscope operation holes 320 are provided for inserting laparoscope instruments of different sizes, preferably 12 mm and 5 mm.

[0048] In this embodiment, the laparoscope operation hole 320 includes a first laparoscope operation hole 321 and a second laparoscope operation hole 322. The diameter of the first laparoscope operation hole 321 is larger than that of the second laparoscope operation hole 322, and is intended to accommodate surgical instruments of different sizes to improve the flexibility and safety of the operation. By providing two operation holes of different diameters, the most suitable laparoscope operation hole 320 can be flexibly selected according to actual needs during the operation, which not only ensures the effective use of large surgical instruments, but also avoids unnecessary tissue damage and gas leakage in pneumothorax caused by small instruments passing through large holes.

[0049] The endoscope hole 330 and the laparoscope operation hole 320 are each equipped with at least one petal-shaped sealing piece 360. Each sealing piece 360 ​​is made of a flexible material and is designed to be dynamically deformed around the surgical instrument. When the surgical instrument is inserted, the petal sealing piece 360 ​​can form a seal close to the surface of the instrument, effectively preventing excessive loss of gas during the operation, maintaining stable air pressure in the abdominal cavity, and reducing the risk of contamination of the surgical site.

[0050] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
