Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a laparoscopic suction retractor. Background Art

[0002] With the continuous advancement of modern medical technology, laparoscopic surgery has been widely used in clinical practice due to its advantages of less trauma, faster recovery and fewer complications. In laparoscopic surgery, doctors use a laparoscope lens and various surgical instruments through a small hole in the abdominal wall to perform surgery, achieving minimally invasive treatment of the patient's internal organs.

[0003] However, in the existing laparoscopic surgery technology, 3-4 holes need to be opened to place different instruments. Among them, the titanium clamp and the aspirator are two independent surgical instruments. The titanium clamp pulls the visceral tissue, and the aspirator sucks the smoke, blood and fluid produced by electrocoagulation. They need to occupy two different holes for placement. Although this setting method meets the needs of surgical operations to a certain extent, it also has the following significant defects:

[0004] 1. Increased surgical holes: Since the titanium clamp and the suction device each need to occupy a hole, more holes need to be made on the patient's abdominal wall during the operation, increasing the patient's trauma and surgical risks.

[0005] 2. Complex surgical operation: The setting of multiple hole positions increases the complexity of surgical operation. Doctors need to operate multiple instruments at the same time, which puts higher requirements on the surgeon's operating skills and experience.

[0006] 3. Increased surgical costs: The need for additional holes and surgical instruments leads to increased surgical costs, which increases the financial burden on patients.

[0007] 4. Prolonged postoperative recovery time: The setting of multiple holes may increase the risk of postoperative infection and prolong the patient's postoperative recovery time.

[0008] Therefore, it is necessary to improve the existing laparoscopic surgical instruments to reduce the number of surgical holes, simplify the surgical operation, reduce the cost of surgery, and improve the surgical effect and the quality of postoperative recovery of patients.

[0011] The beneficial effects of the utility model are as follows: by arranging a suction tube in the pull rod of the titanium clamp, the titanium clamp body can have both the pulling of visceral tissue and the suction of smoke, blood and fluid generated by electrocoagulation without changing the pipe size of the original titanium clamp body. No additional holes need to be opened to set up a suction device, which can reduce the number of holes opened during the operation.

[0023] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0024] like Figure 1-2 As shown, Example 1 is a laparoscopic suction retractor, including a titanium clamp body, a pull rod 1 of the titanium clamp body being hollow, a suction tube 2 being arranged inside the pull rod 1, a rear end of the suction tube 2 extending out of a rear end of a handle 3 of the titanium clamp body and connected to a push button 4, the push button 4 is pressed or released relative to the handle 3 to extend or retract the front end of the suction tube 2 into or out of the titanium clamp body, the rear end of the suction tube 2 passes through the push button 4 and is externally connected to a negative pressure suction device.

[0025] By setting a suction tube 2 in the pull rod 1 of the titanium clamp, without changing the pipe size of the original titanium clamp body, the titanium clamp body can have both the traction of visceral tissue and the suction of smoke, blood and fluid generated by electrocoagulation. There is no need to open additional holes to set up a suction device, which can reduce the number of holes opened during the operation. In addition, the design of the push button 4 can enable the suction tube 2 to extend out of the front end of the titanium clamp body when in use, and retract into the pull rod 1 when not in use, without affecting the traction of the titanium clamp body on the visceral tissue.

[0026] Embodiment 2: This embodiment is a further improvement on the basis of embodiment 1, and its details are as follows:

[0027] The titanium clamp body also includes a sleeve 5 and a clamping mechanism 6; the sleeve 5 is sleeved on the outside of the pull rod 1, the rear end of the sleeve 5 is connected to the front end of the handle 3, and the rear end of the pull rod 1 is fixedly connected to the movable end of the handle 3; the clamping mechanism 6 includes an upper bite portion 61, a lower bite portion 62, an upper connecting rod 63 and a lower connecting rod 64; the rear end of the upper bite portion 61 is rotatably connected to the upper front end of the sleeve 5, the rear end of the lower bite portion 62 is rotatably connected to the lower front end of the sleeve 5, one end of the upper connecting rod 63 is rotatably connected to the middle of the upper bite portion 61, and the other end is rotatably connected to the upper front end of the pull rod 1, one end of the lower connecting rod 64 is rotatably connected to the middle of the lower bite portion 62, and the other end is rotatably connected to the lower front end of the pull rod 1.

[0028] By pressing the movable end of the handle 3, the pull rod 1 is driven to pull the upper connecting rod 63 and the lower connecting rod 64 toward the rear end, thereby driving the upper bite part 61 and the lower bite part 62 to move closer to the middle and bite, so as to pull the visceral tissue.

[0029] In a specific implementation, the fixed end of the handle 3 extends downward to form a grip rod, the movable end of the handle 3 is hinged to the upper part of the grip rod, and the two are open in an eight-shaped shape when not in use, and the upper part of the movable end of the handle 3 extends into the cavity of the fixed section of the handle 3 and is fixedly connected to the collar at the rear end of the pull rod 1. When the movable end of the handle 3 is pressed relative to the grip rod, the upper part of the movable end of the handle 3 moves backward, driving the collar to pull the pull rod 1 backward along the suction tube 2.

[0030] Embodiment 3, this embodiment is a further improvement on the basis of embodiment 1, and its details are as follows:

[0031] A first limiting ring 51 is provided inside the front end of the sleeve 5, a second limiting ring 11 is provided on the outer peripheral wall of the pull rod 1, and a first reset spring 7 is sleeved between the first limiting ring 51 and the second limiting ring 11 outside the pull rod 1. When the movable end of the handle 3 is released, under the action of the first reset spring 7, the pull rod 1, the upper bite part 61, the lower bite part 62, the upper connecting rod 63 and the lower connecting rod 64 will automatically reset, and the upper bite part 61 and the lower bite part 62 will separate to facilitate the next clamping and pulling, without manual reset, and the operation is more convenient.

[0032] Embodiment 4: This embodiment is a further improvement on the basis of embodiment 1, and its details are as follows:

[0033] The suction tube 2 is sleeved with a second return spring 8, which is arranged between the push button 4 and the handle 3. When the push button 4 is released, the suction tube 2 will automatically return to its original position under the action of the second return spring 8 and retract into the pull rod 1, so as to facilitate the next suction without manual return, which is more convenient to operate.

[0034] Embodiment 5, this embodiment is a further improvement on the basis of embodiment 1, and its details are as follows:

[0035] The upper bite part 61, the lower bite part 62, the upper connecting rod 63 and the lower connecting rod 64 are all made of titanium alloy. The titanium alloy material commonly used in medical instruments makes the device more durable and safer to use.

[0036] Embodiment 6: This embodiment is a further improvement on the basis of embodiment 1, and its details are as follows:

[0037] The adjacent surfaces of the upper bite portion 61 and the lower bite portion 62 are respectively provided with anti-slip teeth 6121. The bite is more secure during the pulling process.

[0038] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present invention.
