Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a self-drip bipolar electrocoagulation forceps. Background Art

[0002] At present, bipolar electrocoagulation has become an indispensable surgical instrument in some delicate surgical operations. However, traditional bipolar electrocoagulation can easily carbonize nerves and blood vessels, or cause eschar to adhere to the forceps tip, causing electric burns to surrounding tissues, and the forceps tip needs to be wiped frequently, affecting the surgical process and prolonging the operation time. The dripping bipolar electrocoagulation forceps currently used in clinical practice usually require a doctor to control the dripping, and the dripping speed and timing are difficult to control, and waste manpower.

[0003] The existing application number is CN201820010170.1, which is a kind of dripping bipolar electrocoagulation forceps, including a double-flap forceps body, each of which includes a forceps handle, a conductive working tip and a catheter. The surface of the catheter near the water outlet is provided with an incision for inserting the conductive working tip; the section from the incision to the catheter outlet is the fixed part, and the section from the incision to the catheter outlet is the diversion part; the fixed part is sleeved on the conductive working tip, and the tip of the conductive working tip is inserted through the incision and passed through by the water outlet of the catheter; the diversion part is fixed on the forceps handle; a flow regulator is sleeved on the diversion part; and the water inlet end of the catheter is connected to an infusion bottle. However, in this technology, when the doctor uses the bipolar electrocoagulation forceps, he needs to press and hold the control switch to close the catheter. If the control switch needs to be pressed for a long time, it may cause soreness in the doctor's fingers, increasing the probability of surgical errors. Summary of the invention

[0004] The purpose of the present invention is to provide a self-drip bipolar electrocoagulation forceps to achieve long-term self-sealing and self-connection of a catheter, reduce the workload of doctors, and improve ease of use.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A self-drip bipolar electrocoagulation forceps comprises an electrode seat, forceps handles are provided on both sides of the electrode seat, and a conductive tip is connected to one end of the forceps handle away from the electrode seat, wherein a flow guide tube is provided on one of the forceps handles, and the water outlet of the flow guide tube is in contact with the inner wall of the conductive tip, and a control mechanism for controlling the flow guide tube is sleeved on the forceps handle, and the control mechanism comprises a control shell sleeved on the forceps handle, and a through hole for penetrating the flow guide tube is provided on the control shell, and a control slot is provided in the control shell, and a control rod is movably provided in the control slot, and a pressing rod is provided at one end of the control rod facing the through hole, and a control button is connected to the other end of the control rod, and the control button is slidably connected to the control slot, and a first spring sleeved on the pressing rod is provided at one end of the control slot near the through hole, and the other end of the first spring is connected to the control rod, and an elastic limiting plate is provided on the control rod, and a limiting block is provided at one end of the elastic limiting plate away from the control rod, and a closing slot connected to the control slot is provided outside the control shell, and the closing slot is adapted to the limiting block.

[0007] By adopting the above scheme, when the electrocoagulation forceps need to be used, the physiological saline introduced from the outside by the drainage tube cools the electrocoagulation forceps, reduces the adhesion of blood and tissue, and facilitates the doctor to perform surgery; but when the doctor does not want the electrocoagulation forceps to drip, the control button is pressed to drive the control rod to abut the pressing rod with the drainage tube, and the drainage tube in the through hole is closed. At this time, the limit block of the elastic limit plate on the control rod is engaged with the closing groove to complete the fixation, which reduces the doctor's work intensity during surgery and improves the convenience during surgery; when the electrocoagulation forceps need to drip, the doctor can press the limit block with a tool or hand to make it escape from the closing groove. Under the action of the first spring, the control rod moves toward the control button, drives the pressing rod to release the abutment with the drainage tube, and the drainage tube is unblocked, and the dripping function is restarted. This method is simple to control, is convenient for doctors to operate, reduces the doctor's work intensity, and improves the convenience of use; not only the long-term self-sealing and self-connection of the drainage tube are achieved, but also the deformation degree of the drainage tube can be controlled by pressing the control button to control the dripping speed (when the control button is not pressed to the bottom).

[0008] Preferably, an elastically bent limit release plate is provided on the top of the control button, and a first release block adapted to the limit release plate is provided facing the closing groove.

[0009] Preferably, the limit release plate is slidably connected to the control button, and a second spring is provided between the limit release plate and the control button.

[0010] Preferably, a plurality of constant flow grooves adapted to the limit blocks are provided outside the control housing, and a second release block is provided on the limit release plate facing the constant flow grooves.

[0011] Preferably, a control lever is provided on the top of the limit release plate.

[0012] Preferably, the pressing rod is configured to be arc-shaped at one end facing the through hole.

[0013] The present invention has the following beneficial effects:

[0014] 1. When the electrocoagulation forceps need to be used, the physiological saline introduced from the outside by the drainage tube cools the electrocoagulation forceps, reduces the adhesion of blood and tissue, and facilitates the doctor to perform surgery; but when the doctor does not want the electrocoagulation forceps to drip, the control button is pressed to drive the control rod to abut the pressing rod with the drainage tube to complete the closure of the drainage tube in the through hole. At this time, the limit block of the elastic limit plate on the control rod is engaged with the closing groove to complete the fixation, which reduces the doctor's work intensity during surgery and improves the convenience during surgery; when the electrocoagulation forceps need to drip, the doctor can press the limit block with a tool or hand to make it disengage from the closing groove. Under the action of the first spring, the control rod moves toward the control button, drives the pressing rod to release the abutment with the drainage tube, and the drainage tube is unblocked, restarting the dripping function. This method is simple to control, is conducive to the doctor's operation, reduces the doctor's work intensity, and improves the convenience of use; not only the long-term self-closure and self-connection of the drainage tube are realized, but also the deformation degree of the drainage tube can be controlled by pressing the control button to control the dripping speed (when the control button is not pressed to the bottom);

[0015] 2. A limit release plate is provided to provide doctors with a tool that is more convenient for controlling the limit block, further improving the convenience of control;

[0016] 3. A constant flow groove is set, and the limit blocks are adapted to different constant flow grooves in turn, thereby adjusting the deformation degree of the guide tube in the through hole in turn, thereby controlling the flow rate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] A self-drip bipolar electrocoagulation forceps, such as Figure 1-2As shown, it includes an electrode seat 1, and forceps handles 2 are provided on both sides of the electrode seat 1. The ends of the forceps handles 2 away from the electrode seat 1 are connected to conductive tips 3, one of the forceps handles 2 is provided with a flow guide tube 4, and the water outlet of the flow guide tube 4 is in contact with the inner wall of the conductive tip 3. The forceps handles 2 are sleeved with a control mechanism for controlling the flow guide tube 4, and the control mechanism includes a control shell 51 sleeved on the forceps handle 2, and the control shell 51 is provided with a through hole 53 for penetrating the flow guide tube 4. The control shell 51 is provided with a control groove 52, and a control rod 55 is movably provided in the control groove 52, and the control rod 55 is directed toward the through hole A pressing rod 56 is provided at one end of the control rod 53, and a control button 54 is connected to the other end of the control rod 55. The control button 54 is slidably connected to the control slot 52. A first spring 57 is provided on the pressing rod 56 at one end of the control slot 52 near the through hole 53. The other end of the first spring 57 is connected to the control rod 55. An elastic limiting plate 58 is provided on the control rod 55.

[0022] like Figure 1-2 As shown, by adopting the above scheme, when the electrocoagulation forceps are needed, the saline introduced from the outside by the guide tube 4 cools down the electrocoagulation forceps, reduces the adhesion of blood and tissue, and facilitates the doctor to perform the operation; but when the doctor does not want the electrocoagulation forceps to drip, the control button 54 is pressed to drive the control rod 55 to abut the pressing rod 56 against the guide tube 4, so as to complete the closure of the guide tube 4 in the through hole 53. At this time, the limit block 59 of the elastic limit plate 58 on the control rod 55 is engaged with the closing groove 510 to complete the fixation, thereby reducing the doctor's work intensity during the operation and improving the convenience during the operation; when the electrocoagulation forceps are needed to drip, the doctor The doctor can use a tool or hand to press the limit block 59 to make it escape from the closed groove 510. Under the action of the first spring 57, the control rod 55 moves toward the control button 54, driving the pressing rod 56 to release the contact with the guide tube 4, so that the guide tube 4 is unblocked and the dripping function is restarted. This method is simple to control, convenient for doctors to operate, reduces the workload of doctors, and improves ease of use.
