Description

Technical Field

[0001] The invention relates to an electrocoagulation forceps, in particular to an electrocoagulation forceps with enhanced insulation and leakage protection. Background Art

[0002] As a common tool in minimally invasive surgery, electrocoagulation forceps are mainly used for hemostasis under laparoscopy. Based on the safety of bipolar electrocoagulation technology, bipolar electrocoagulation forceps are widely used in minimally invasive surgery. However, the insulation protection structure of existing electrocoagulation forceps is not good enough, and there is not enough creepage distance. It is particularly easy for leakage to occur between the two jaws. The high-frequency electrical effect generated by the leakage will damage normal tissue, affect the efficiency of the operation and reduce the safety of the operation. And when leakage occurs, it may not be detected in time, and continuous leakage will cause greater damage to normal tissue. Summary of the invention

[0003] According to the technical problem raised above, an electrocoagulation forceps with enhanced insulation belt leakage protection is provided. The technical means adopted by the present invention are as follows:

[0004] A coagulation forceps with enhanced insulation and leakage protection, the coagulation forceps comprising a sleeve, a first jaw, a second jaw, a first handle, a second handle and a pull rod, a fork is installed at one end of the sleeve, the first jaw and the second jaw are respectively provided with a first mounting end and a second mounting end at the rear ends, the first mounting end and the second mounting end are both installed in the fork, the first mounting end and the second mounting end are hinged by a first hinge shaft, the second mounting end and the side wall of the fork close to the second mounting end are hinged by a second hinge shaft, the tail end of the first mounting end is hinged to one end of the pull rod; the other end of the pull rod axially passes through the fork bottom of the fork and the sleeve and is connected to the first handle, the end of the sleeve away from the fork is fixedly connected to the second handle, and the first handle is hinged to the second handle, the first jaw has a first jaw surface, the second jaw has a second jaw surface, and a reinforced insulation structure is provided between the first mounting end and the second mounting end, which is located in the fork and can prevent the first mounting end and the second mounting end from leakage during operation;

[0005] The first handle is equipped with a current leakage protection module. The current leakage protection module model is HCPL-7840;

[0006] The current leakage protection module includes an ARM processor, and the ARM processor is electrically connected to the active motor, the first jaw, and the second jaw respectively. The ARM processor integrates and calculates the current value flowing into and out of the electrocoagulation forceps, compares and analyzes the two values, calculates the difference, and then compares and judges with the preset protection threshold. If it is higher than the protection threshold, the circuit between the active motor and the electrocoagulation forceps is disconnected, and the power supply output is cut off.

[0007] The reinforced insulation structure comprises an insulation seat and an insulation sleeve;

[0008] The insulating seat is an integrated structure formed by a first insulating plate, a second insulating plate and a third insulating plate;

[0009] The first insulating plate is mounted on a side wall of the fork near the first jaw and matches the side wall of the fork; the second insulating plate is mounted on the fork bottom of the fork and matches the fork bottom of the fork, and one end of the second insulating plate is fixedly connected to the tail end of the first insulating plate; the third insulating plate is mounted on a side wall of the fork near the second jaw, and the tail end of the third insulating plate is fixedly connected to the other end of the second insulating plate, and the front end of the third insulating plate is at the rear side of the tail end of the first mounting end;

[0010] The insulating sleeve is installed on the first installation end, and the insulating sleeve is an integrated structure consisting of a first insulating sleeve, a second insulating sleeve and a third insulating sleeve;

[0011] The first insulating sleeve is installed on the side wall of the first mounting end close to the second mounting end and matches this side wall of the second mounting end; the second insulating sleeve is installed on the side wall of the first mounting end close to the first clamp surface and matches this side wall of the first mounting end, the first insulating sleeve is fixedly connected to the second insulating sleeve, the third insulating sleeve wraps the rear end side wall of the first jaw and the rear end outer wall of the first clamp surface, and the second insulating sleeve and one end of the first insulating sleeve close to the third insulating sleeve are fixedly connected to the third insulating sleeve.

[0012] A spherical head is processed at one end of the pull rod close to the first handle, and a vertically arranged rectangular groove is processed in the first handle, and the spherical head is installed in the rectangular groove.

[0013] The reinforced insulating device is coated with a nano-hydrophobic coating to prevent liquid from remaining and forming a current path between the insulating parts of the first jaw and the second jaw.

[0014] The first hinge shaft and the second hinge shaft are both made of insulating materials.

[0015] The structural design of the insulating sleeve and the insulating seat can enhance the rigidity of the insulating material and completely isolate the first mounting end and the second mounting end, that is, isolate the ends of the first jaw and the second jaw, so that they are completely isolated when not working.

[0016] The present invention has the following advantages:

[0017] 1. To increase safety during surgery, the conductive paths of the first jaw and the second jaw are completely separated by insulating materials and spatially separated to ensure that the non-working ranges of the two jaws will not touch each other.

[0018] 2. The current leakage protection module determines whether leakage occurs by analyzing and comparing the current flowing through the first jaw and the second jaw. If leakage occurs, the output of the main surgeon motor to the electrocoagulation forceps is disconnected to protect the patient's safety.

[0019] Based on the above reasons, the present invention can be widely promoted in the fields of electrocoagulation forceps and the like. BRIEF DESCRIPTION OF THE DRAWINGS
