Description

Technical Field

[0001] The invention relates to an auxiliary tool for laparoscopic surgery, in particular to an electric screw-in puncture card. Background Art

[0002] With the development of medical technology, minimally invasive surgeries with less damage and quick recovery have become very popular in the medical field. Among them, laparoscopes play a very important role in many minimally invasive surgeries. Laparoscopes are mostly inserted into the body through laparoscopes.

[0003] The laparoscopic puncture clamps in the prior art are mostly composed of a puncture clamp core and a puncture clamp sleeve. The puncture clamp core is inserted into the puncture clamp sleeve and punctures the puncture hole in the abdominal wall together. Since the puncture clamp core is handheld and directly punctures the abdominal wall, in order to avoid accidental damage to the internal organs, the puncture depth and force accuracy requirements are very high, and it needs to be completed by professional medical personnel. The operation is quite difficult.

[0004] In addition, when the puncture tube enters the abdominal wall or during the operation, the puncture tube is easy to slide in the puncture hole of the abdominal wall, affecting the laparoscopic surgical field and the operation. In order to avoid the puncture tube from sliding, the surface of the puncture tube in the prior art is provided with a frosted surface or anti-skid pattern for increasing friction, which improves the stability of the puncture tube in the abdominal wall. However, the frosted surface or anti-skid pattern rubs and squeezes the body tissue, which not only causes friction damage and bleeding at the surgical puncture hole, but also brings unnecessary pain to the patient. When the puncture tube is removed, the frosted surface or anti-skid pattern will cause damage to the puncture hole again, which is not conducive to postoperative recovery.

[0005] The laparoscopic puncture card of the prior art still has various shortcomings, such as:

[0006] 1. Since body tissues are soft and elastic, the existing puncture needle will cause increased abdominal pressure when inserted into the abdominal cavity, which is not conducive to the abdominal needle body piercing the abdominal wall. Medical staff need to puncture repeatedly, causing greater harm to the patient.

[0007] 2. In order to adapt to the use of patients of different body shapes, the existing puncture card core and puncture card sleeve need to reserve sufficient length and volume to ensure that the puncture depth and angle can meet the surgical requirements. However, the length of surgical instruments such as laparoscopes is limited. The excessive length and volume of the puncture card can easily affect the surgical field of view, which is not conducive to the progress of the operation. Summary of the invention

[0008] The purpose of the present invention is to provide an electric screw-in puncture card, which can be tightened and screwed into the surgical puncture hole through a thread, reducing damage to the surgical puncture hole tissue, facilitating the insertion and positioning of the puncture card in the abdominal wall, assisting the smooth progress of laparoscopic surgery, and also facilitating postoperative recovery.

[0009] The present invention is achieved in that:

[0010] An electric screw-in poking card comprises an electric control handle, a poking card sleeve and a poking card core; the electric control handle comprises a handle shell and a screw-in control component arranged in the handle shell, the output end of the screw-in control component is provided with a coupling bayonet, one end of the poking card sleeve is provided with a control connection part matching the coupling buckle, the control connection part is connected to the electric control handle through the coupling bayonet, so that the poking card sleeve can be rotated by the screw-in control component; the poking card sleeve is a hollow tubular structure, and a first screw-in thread is provided on the outer tube wall of the poking card sleeve; one end of the poking card core is provided with a clamping part, the poking card core passes through the control connection part and the poking card sleeve, the needle tip of the poking card core extends to the outside of the other end of the poking card sleeve, and the clamping part is matched and clamped with the control connection part, so that the poking card core and the poking card sleeve are synchronously screwed into the surgical poking port, and are in tension contact with the inner wall of the poking port through the first screw-in thread.

[0011] The screw-in control component includes a power supply, a microcontroller, a plurality of gear shift switches and their time relays, a rotating motor and a forward and reverse control button; the plurality of gear shift switches and the forward and reverse control button are embedded in the handle housing of the electric control handle, and the power supply, the microcontroller, the time relay and the rotating motor are arranged in the handle housing; the gear shift switch and its corresponding time relay are connected in series to form a gear shift circuit, and the plurality of gear shift circuits are connected in parallel with the power supply, the microcontroller, the rotating motor and the forward and reverse control button to form a control circuit; the output shaft of the rotating motor is connected to the combining buckle, so that the rotating motor can drive the punching sleeve to rotate forward or reverse through the combining buckle.

[0012] A second screw-in thread is arranged on the outer wall of the needle tip of the piercing core, and the second screw-in thread is located outside the piercing sleeve.

[0013] The second screw-in thread is connected to the first screw-in thread, and the second screw-in thread and the first screw-in thread have the same rotation direction and pitch.

[0014] The length of the piercing sleeve is 5-10 cm.

[0015] The diameter of the piercing sleeve is 5-15 mm.

[0016] The outer diameter of the control connection part is larger than the outer diameter of the piercing sleeve.

[0017] The inner diameter of the piercing sleeve is larger than the diameter of the piercing core, and the needle tip extending outside the piercing sleeve is a conical structure and smoothly transitions with the outer tube wall of the piercing sleeve.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention adopts an electric control handle to control the insertion of the puncture card into the surgical puncture port. The insertion depth is precisely controllable, which effectively avoids the damage to the internal organs caused by the puncture card being inserted too deeply, and also avoids the problem of limited laparoscopic field of view caused by the puncture card being too long and too large in size.

[0020] 2. The present invention uses the first screw-in thread and the second screw-in thread to assist the puncture card to be screwed into and tightened in the surgical puncture hole of the abdominal wall, and can minimize frictional damage to body tissues when screwing in, and will not rub or slide against the abdominal wall during surgery, thereby reducing damage to the patient and facilitating postoperative recovery.

[0021] 3. The present invention is easy to use and easy to assemble and disassemble. It does not require high professionalism and operating experience of the operator and is suitable for assisting various laparoscopic surgeries. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] Please see attached Figure 1 and attached Figure 2, an electric screw-in poking card, comprising an electric control handle 1, a poking card sleeve 2 and a poking card core 3; the electric control handle 1 comprises a handle shell and a screw-in control component arranged in the handle shell, the output end of the screw-in control component is provided with a coupling bayonet 11, one end of the poking card sleeve 2 is provided with a control connection part 21 matching the coupling buckle 11, the control connection part 21 is connected to the electric control handle 1 through the coupling bayonet 11, so that the poking card sleeve 2 can be rotated by the screw-in control component; the poking card sleeve 2 is a hollow tubular structure, and a first screw-in thread 22 is provided on the outer tube wall of the poking card sleeve 2; one end of the poking card core 3 is provided with a clamping part 31, the poking card core 3 passes through the control connection part 21 and the poking card sleeve 2, the needle tip 32 of the poking card core 3 extends to the outside of the other end of the poking card sleeve 2, and the clamping part 31 is matched with the control connection part 21, so that the poking card core 3 and the poking card sleeve 2 are synchronously screwed into the surgical poking port, and are in tension contact with the inner wall of the poking port through the first screw-in thread 22.

[0028] Please see attached Figure 3 The screw-in control assembly includes a power supply 12, a microcontroller 13, a plurality of gear-adjusting switches 14 and their time relays 15, a rotating motor 16 and a forward and reverse control button 17; the plurality of gear-adjusting switches 14 and the forward and reverse control button 17 are all embedded in the handle housing of the electric control handle 1, and the power supply 12, the microcontroller 13, the time relay 15 and the rotating motor 16 are arranged in the handle housing; the gear-adjusting switches 14 and their corresponding time relays 15 are connected in series to form a gear-adjusting circuit, and the plurality of gear-adjusting circuits are connected in parallel with the power supply 12, the microcontroller 13, the rotating motor 16 and the forward and reverse control button 17 to form a control circuit; the output shaft of the rotating motor 16 is connected to the coupling buckle 11, so that the rotating motor 16 can drive the coupling buckle 11 to rotate forward or reverse, thereby controlling the synchronous rotation of the poking card sleeve 2 and the poking card core 3.

[0029] A second screw-in thread 33 is arranged on the outer wall of the needle tip 32 of the puncture core 3. The second screw-in thread 33 is located outside the puncture sleeve 2 and can assist the needle tip 32 to be screwed into the surgical puncture port.

[0030] The first screw-in thread 22 is connected to the second screw-in thread 33, and the first screw-in thread 22 and the second screw-in thread 33 have the same rotation direction and pitch, further ensuring that the puncture card core 3 and the puncture card sleeve 2 can be smoothly screwed into the surgical puncture port. The first screw-in thread 22 and the second screw-in thread 33 can be connected by means of concave-convex positioning clamping to achieve positioning connection, further reducing the friction on the inner wall of the surgical puncture port.

[0031] Preferably, the length of the puncture sleeve 2 is 5-10 cm, which not only ensures that the puncture depth meets the surgical requirements, but also avoids the requirement for the length of the surgical instrument and does not affect the surgical field of view.

[0032] Preferably, the diameter of the puncture sleeve 2 is about 5-15 mm, which can be suitable for surgical puncture ports of different calibers to meet different surgical requirements.

[0033] Preferably, the outer diameter of the control connection part 21 is larger than the outer diameter of the puncture sleeve 2. By pressing the skin surface with the control connection part 21 with a larger outer diameter, the puncture sleeve 2 can be further prevented from being screwed in further after being fully screwed in, thereby avoiding excessive puncture depth.

[0034] Preferably, the inner diameter of the puncture card sleeve 2 is slightly larger than the diameter of the puncture card core 3, and the needle tip 32 extending to the outside of the puncture card sleeve 2 is a conical structure and smoothly transitions with the outer tube wall of the puncture card sleeve 2, so that the puncture card sleeve 2 can be synchronously screwed into the surgical puncture port along with the puncture card core 3, avoiding damage to the surgical puncture port tissue caused by the concave-convex structure of the transition section due to the large size difference.

[0035] Before performing laparoscopic surgery, a puncture tube 2 and a puncture core 3 of suitable diameter are selected according to the size of the surgical puncture incision and the requirements of the surgery, and the puncture core 3 is inserted into the puncture tube 2. The conical needle tip 32 of the puncture core 3 penetrates the outside of the puncture tube 2, and the clamping part 31 of the puncture core 3 is connected to the control connection part 21 of the puncture tube 2. The clamping part 31 and the control connection part 21 can be clamped and rotated synchronously by matching concave and convex openings, etc., which also facilitates the insertion and removal of the puncture core 3. The piercing sleeve 2 is connected to the electric control handle 1 through the control connection part 21 via the combination bayonet 11. The control connection part 21 and the combination bayonet 11 can be connected and rotated synchronously by means of concave and convex openings, and ensure that the thread lines of the first screw-in thread 22 and the second screw-in thread 33 are connected. The insertion depth is judged according to the patient's body shape and other conditions. The needle tip 32 of the piercing core 3 is aligned with the surgical piercing port. The electric control handle 1 controls the piercing sleeve 2 and the piercing core 3 to rotate synchronously. The principle is the same as that of screwing in a bolt. Only a small force needs to be applied, and the piercing sleeve 2 and the piercing core 3 can be screwed into the abdominal wall through the first screw-in thread 22 and the second screw-in thread 33 through the surgical piercing port. Due to the convex thread structure of the first screw-in thread 22 and the second screw-in thread 33, they can be in tight contact with the abdominal wall body tissue, which will not cause frictional damage to the tissue, and at the same time facilitate the screwing of the piercing sleeve 2 and the piercing core 3. After being screwed into place, the electric control handle 1 is removed, and the piercing card core 3 is taken out through the concave-convex structure. The piercing card sleeve 2 is tightened and fixed in the surgical piercing opening through the first screw-in thread 22, and laparoscopic surgery can be performed.

[0036] The method for controlling the screwing depth of the punching sleeve 2 of the present invention is specifically as follows: according to the screwing depth requirement, the corresponding gear shift switch 14 on the electric control handle 1 is pressed, and the forward and reverse control button 17 is used to control the forward rotation of the rotary motor 16. The microcontroller 13 controls the time relay 15 corresponding to the gear shift switch 14 to set the rotation time of the rotary motor 16. Since the rotary motor 16 rotates at a constant speed, the number of rotations of the punching sleeve 2 can be controlled by the rotary motor 16. Since the pitches of the first screwing thread 22 and the second screwing thread 33 are equivalent, the screwing depth of the punching sleeve 2 can be accurately controlled by the number of rotations. After the punching is in place, the time relay 15 controls the rotary motor 16 to stop running. The power supply 12 provides electrical energy for the screw-in control component. Several gear switches 14 can be preset to 5 cm gear, 6 cm gear and 7 cm gear according to surgical needs. Each gear switch 14 is equipped with a corresponding time relay 15, and the operating time of the rotating motor 16 is controlled accordingly to ensure that the time relay 15 cuts off the power supply after the screw-in depth reaches the set value, and the rotating motor 16 stops running and no longer continues to screw in.

[0037] After the operation, the electric control handle 1 can be reinstalled on the control connection part 21 of the puncture tube 2 by combining with the bayonet 11, and the rotating motor 16 can be controlled to rotate in the opposite direction by the forward and reverse control button 17, and the appropriate gear shift switch 14 can be selected to make the rotating motor 16 drive the puncture tube 2 to rotate out of the abdominal wall, and the surgical puncture can be sutured.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
