Description

Technical Field

[0001] This utility model relates to the technical field of single-hole multi-channel puncture devices, specifically a support-type single-hole multi-channel puncture device. Background Technology

[0002] With the development of medical technology, minimally invasive laparoscopic surgery has been increasingly promoted and used in China. Laparoscopic surgery often employs a 2-4 port approach, with one incision made in the navel or another part of the abdomen, avoiding long, linear scars in the abdominal cavity. After recovery, only 1-3 linear scars of 0.5-1 cm remain in the abdominal cavity. It can be described as a surgery with small incisions and minimal pain, hence the name "keyhole" surgery. The development of laparoscopic surgery has reduced the pain of open surgery, shortened the recovery period, and relatively reduced patient expenses, making it a rapidly developing surgical procedure in recent years.

[0003] Existing single-port multi-channel trocars require a small incision of approximately 1.5-3 cm in the patient's abdomen before insertion of the lower end of the trocar into the abdominal cavity. The inner clasp of the incision protector is then secured to the abdominal wall. Gas is then introduced into the balloon to inflate it, thus fixing the trocar to the abdominal surface. However, the balloon, in conjunction with the inner clasp, needs to work to secure the trocar. Because patients' skin thickness varies, a certain length of the incision protector may remain after fixation. Removing and replacing the trocar is cumbersome. Continuing to use the trocar during surgery can cause significant movement when surgical instruments come into contact with it, potentially damaging the abdominal incision and hindering wound healing. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a support-type single-port multi-channel trocar, which solves the problem of patients having varying skin thicknesses. After fixation, a certain length of incision protective sleeve may remain at the upper end, making it cumbersome to disassemble and replace the single-port multi-channel trocar. Furthermore, if the single-port multi-channel trocar is used for surgery, significant shaking can easily occur when surgical instruments come into contact with it, causing damage to the abdominal incision and affecting the subsequent healing of the patient's wound.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a support-type single-hole multi-channel puncture device, including an incision protective sleeve, a mechanical channel fixedly installed at the upper end of the incision protective sleeve, an inner retaining ring fixedly installed at the lower end of the incision protective sleeve, and a balloon ring sleeved on the outer surface of the incision protective sleeve;

[0008] The support mechanism is mounted on the cut protective sleeve. The support mechanism includes two support plates and two snap-fit ​​plates. The two support plates are sleeved on the outer surface of the cut protective sleeve and are arranged in a left-right correspondence. The two support plates are located above the inner snap ring. Two pads are fixedly installed on the lower surface of the two support plates. Two connecting grooves are opened on the left surface of the right support plate. The two snap-fit ​​plates are slidably installed in the two connecting grooves respectively. An L-shaped groove is opened on the right surface of the left support plate corresponding to the position of the two connecting grooves. The left ends of the two snap-fit ​​plates slide into the corresponding L-shaped grooves.

[0009] Preferably, the support mechanism further includes four springs, which are respectively fixedly installed on the adjacent inner walls of the two connecting grooves, and the far ends of the four springs are respectively fixedly connected to the corresponding snap-fit ​​plates.

[0010] Preferably, the support plate on the right side has an installation groove inside, and two toothed plates are slidably installed on the inner wall of the installation groove. The far ends of the two toothed plates slide into the interior of the two connecting grooves, and the two toothed plates are fixedly connected to the corresponding snap-fit ​​plates.

[0011] Preferably, a gear is rotatably mounted on the inner wall of the mounting groove, and both toothed plates are meshed with the gear. A rotating rod is rotatably mounted on the right surface of the right support plate, and the left end of the rotating rod extends rotatably into the interior of the mounting groove. The rotating rod is fixedly connected to the gear.

[0012] Preferably, an air injection valve is fixedly installed on the right side of the mechanical channel.

[0013] Preferably, silicone tubes are fixedly installed at both the front and rear ends of the balloon, and one-way valves are provided at the far ends of the two silicone tubes.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a support-type single-hole multi-channel puncture device, which has the following beneficial effects:

[0016] 1. This support-type single-port multi-channel trocar, through the setting of two support plates and two pads, can support the excess section when there is a certain distance left at the top of the single-port multi-channel trocar, without the need to disassemble or replace the single-port multi-channel trocar, and can continue to be used. It also reduces the shaking amplitude when subsequent surgical instruments come into contact with the single-port multi-channel trocar, thereby improving the efficiency of the single-port multi-channel trocar.

[0017] 2. This support-type single-hole multi-channel puncture device allows two locking plates to enter the corresponding L-shaped grooves by rotating the rotating rod, thus fixing the two support plates. Four springs further fix the two locking plates, making the fixation of the two support plates relatively convenient, but this reduces the efficiency of the support-type single-hole multi-channel puncture device.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4This utility model provides a new technical solution: a support-type single-hole multi-channel puncture device, including an incision protective sleeve 1, a mechanical channel 2 fixedly installed at the upper end of the incision protective sleeve 1, an inner retaining ring 3 fixedly installed at the lower end of the incision protective sleeve 1, and a balloon ring 17 sleeved on the outer surface of the incision protective sleeve 1.

[0025] The support mechanism is set on the cut protective sleeve 1. The support mechanism includes two support plates 4 and two snap-fit ​​plates 5. The two support plates 4 are both sleeved on the outer surface of the cut protective sleeve 1. The two support plates 4 are arranged in a left-right correspondence and are located above the inner snap ring 3. Two pads 6 are fixedly installed on the lower surface of the two support plates 4. The pads 6 are made of silicone. Two connecting grooves 7 are opened on the left surface of the right support plate 4. The two snap-fit ​​plates 5 are slidably installed in the two connecting grooves 7 respectively. The snap-fit ​​plate 5 is a combination of a rectangular plate and a triangular plate. An L-shaped groove 8 is opened on the right surface of the left support plate 4 corresponding to the position of the two connecting grooves 7. The left ends of the two snap-fit ​​plates 5 slide into the corresponding L-shaped grooves 8.

[0026] Furthermore, the support mechanism also includes four springs 9, which are fixedly installed on the adjacent inner walls of the two connecting grooves 7 respectively, and the far ends of the four springs 9 are fixedly connected to the corresponding snap-fit ​​plates 5 respectively.

[0027] Furthermore, by setting up two support plates 4 and two pads 6, when there is a certain distance left at the upper end of the single-hole multi-channel trocar, the two support plates 4 and two pads 6 can support the remaining section, so that the single-hole multi-channel trocar does not need to be disassembled or replaced and can continue to be used. This also reduces the shaking amplitude when subsequent surgical instruments come into contact with the single-hole multi-channel trocar, thus improving the efficiency of the single-hole multi-channel trocar.

[0028] Furthermore, the right support plate 4 has an installation groove 10 inside, and two toothed plates 11 are slidably installed on the inner wall of the installation groove 10. The far ends of the two toothed plates 11 are slidably extended into the interior of the two connecting grooves 7, and the two toothed plates 11 are fixedly connected to the corresponding snap-fit ​​plates 5 respectively.

[0029] Furthermore, a gear 12 is rotatably mounted on the inner wall of the mounting groove 10, and both toothed plates 11 are meshed with the gear 12. A rotating rod 13 is rotatably mounted on the right surface of the right support plate 4, and the left end of the rotating rod 13 extends rotatably into the interior of the mounting groove 10. The rotating rod 13 is fixedly connected to the gear 12.

[0030] Furthermore, by rotating the rotating rod 13, the two snap-fit ​​plates 5 can be inserted into the corresponding L-shaped grooves 8 to fix the two support plates 4, and the four springs 9 can fix the two snap-fit ​​plates 5, thereby further fixing the two support plates 4. Fixing the two support plates 4 is relatively convenient, but it reduces the efficiency of the use of the support-type single-hole multi-channel puncture device.

[0031] Furthermore, an air injection valve 14 is fixedly installed on the right side of the mechanical channel 2.

[0032] Furthermore, silicone tubes 15 are fixedly installed at both the front and rear ends of the balloon coil 17, and one-way valves 16 are provided at the far ends of the two silicone tubes 15.

[0033] Working principle: When using this support-type single-port multi-channel trocar, after inserting the mechanical channel 2 into the abdominal cavity, the inside of the balloon coil 17 is first inflated through two silicone tubes 15. After inflating, if there is still some distance left at the top of the single-port multi-channel trocar, two suitable support plates 4 can be selected and placed on both sides of the incision protective sleeve 1, and then joined together. When the two support plates 4 are joined together, the rotating rod 13 is rotated, causing the rotating rod 13 to drive the gear 12 fixedly connected to it to rotate. The rotation of the gear 12 causes the two toothed plates 11 meshing with it to move closer together, and the two toothed plates 11 move away from each other, causing the two locking plates 5 to move synchronously. The two locking plates 5 move closer to the corresponding springs 9. When spring 9 is compressed, the two locking plates 5 on the right support plate 4 enter the interior of the two L-shaped grooves 8 on the left. Then, the rotating rod 13 is rotated in the opposite direction, which drives the gear 12 to rotate in the opposite direction, causing the two toothed plates 11 to move the two locking plates 5 away from each other. The two locking plates 5 move away from each other inside the two L-shaped grooves 8, causing the triangular plates on the two locking plates 5 to enter the vertical grooves of the L-shaped grooves, thereby fixing the two support plates 4. When there is a distance left at the upper end of the single-hole multi-channel trocar, the two support plates 4 can support the remaining section, so that the single-hole multi-channel trocar does not need to be disassembled or replaced and can continue to be used, reducing the shaking amplitude when subsequent surgical instruments come into contact with the single-hole multi-channel trocar.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
