Description

Technical Field

[0001] The invention relates to the technical field related to medical instruments, and in particular to a separation pliers for insulating and protecting a pliers head. Background Art

[0002] Tissue separation forceps are one of the commonly used instruments in surgical operations. Currently, the separation forceps are a multi-piece stainless steel structure, which is combined through a four-bar hinge mechanism. One end of the four-bar hinge mechanism is connected to the clamp, and the other end is connected to the handle through a wire traction. The handle pulls or releases the wire to control the opening and closing of the clamp, thereby achieving functions such as clamping, separation, and hemostasis of tissues. In existing laparoscopic surgery, when the separation forceps clamp tissue deep in the body cavity and are powered on for electrocoagulation hemostasis, too much metal is exposed, which will burn surrounding tissues.

[0003] The Chinese patent authorization announcement number is CN208145040U, and the authorization announcement date is November 27, 2018. It discloses a medical surgical separation forceps, which uses the relative movement of the push tube and the connecting rod to drive the opening and closing of the separation forceps set at the front end of the connecting rod, including a connecting rod, an elastic member, and two upper and lower clamps arranged oppositely, the clamps are connected to the front end of the connecting rod through the elastic member, the clamps include a clamp handle and a clamp claw, and the clamp claw is connected to the elastic member through the clamp handle; when the two clamps are closed, the clamp claws contact each other; the elastic member refers to two elastic legs made of elastic material, one end of the two elastic legs is respectively connected to the upper and lower two clamp handles arranged oppositely, and the other end is connected to the front end of the connecting rod after merging, and the clamp is restored to an open state under the action of the elastic member after the external force disappears; the clamp claw is an arc shape with a narrow front and a wide back as a whole. The disadvantage of this utility model is that when electrocoagulation hemostasis is performed, the metal part is exposed too much, which is easy to burn the surrounding tissue. Summary of the invention

[0004] The invention aims to overcome the disadvantages of the prior art that too much metal part is exposed and surrounding tissues are easily burned during electrocoagulation hemostasis, and provides a separation forceps with insulating protection for the forceps head to avoid burning surrounding tissues.

[0006] The hand-held rod is used by the user to hold it during use, and a detachable pliers head is installed on the top of the hand-held rod. The pliers head is a working part used for work, and the opening and closing of the pliers head is controlled by an opening and closing assembly installed on the pliers head. Since the connection between the pliers head and the hand-held rod is detachable, the pliers head can be disassembled and different pliers heads can be replaced for use. It is suitable for different scenes and is also easy to clean. During use, when the pliers head is installed, the opening and closing assembly is connected to the moving assembly, and the opening and closing assembly is driven to move by controlling the moving assembly. The movement of the opening and closing assembly can control the opening and closing of the pliers head. One end of the moving assembly passes through the placement cavity and is placed on the outside, which is convenient for the user to control the opening and closing of the gun head. A protective cover is covered on the pliers head exposed to the outside for work. The existence of the protective cover can isolate the exposed part of the pliers head when it is working from the surrounding tissue, thereby preventing the surrounding tissue from being scalded by electrocoagulation during work, thereby achieving the purpose of avoiding scalding the surrounding tissue.

There are two protective sleeves and correspond to the two chucks one by one. The cross-sectional shape of the protective sleeve is U-shaped, and the chuck can be isolated from the outside except for the side in contact with the other chuck. The protective sleeve is made of insulating material, and the connection between the protective sleeve and the chuck is through the card slot on the chuck and the card slot on the chuck. The protective sleeve is moved along the clamping block and the fitting groove is fitted with the chuck, which can better achieve the insulation effect. Such a design can ensure that the protective sleeve fits the chuck better.

[0009] Preferably, a groove is provided on the side of the protective cover away from the other chuck, a pull rod is provided in the groove, one end of the pull rod is connected to the protective cover, the pull rod corresponds to the groove, and the other end of the pull rod is placed outside the groove. A groove is installed on the side of the protective cover away from the other chuck, and the groove is used to install the pull rod. When not in use, the pull rod is pressed into the groove. After use, when the protective cover needs to be removed, there is usually mucus on the protective cover, which makes it difficult to remove. Therefore, after the pull rod is pulled out of the groove, the protective cover can be pulled apart from the chuck by the pull rod. Such a design facilitates the removal of the protective cover.

[0010] Preferably, a plurality of sawtooth grooves are provided on the opposite sides of the two clamps. The sawtooth grooves are provided on the corresponding sides of the two clamps. The existence of the sawtooth grooves can increase the friction force during use, and such a design facilitates clamping.

The rotation of the rotating block can be further controlled by controlling the opening and closing of the upper end of the twisted rod. The opening and closing of the twisted rod is connected by an extrusion rod. One end of the extrusion rod is rotatably connected to the twisted rod, and the other end is rotatably connected to the push plate. The two extrusion rods are connected to the movement of the push plate. When the push plate pushes the extrusion rod, it can ensure that the extrusion rods are opened on both sides. When the extrusion rod is opened, the twisted rod can be driven to open a certain angle. Driven by the twisted rod, the rotating block rotates, and the chuck can follow the rotating block to rotate around the fixed rod 1, thereby realizing the opening and closing of the pliers head. This design is convenient for controlling the opening and closing of the pliers head.

[0012] Preferably, one end of the twist rod connected to the extrusion rod is in an arc shape, a baffle is installed in the mounting hole, a spring is arranged on the baffle, one end of the spring is connected to the baffle, and the other end of the spring is connected to the push plate. One end of the twist rod and the extrusion rod is in an arc shape, and the arc-shaped twist rod can better drive the rotation angle of the twist rod when being squeezed by the extrusion rod, and can also ensure that the extrusion rod has a certain angle at the initial position, so as to ensure that the opening and closing directions of the two extrusion rods are fixed when opening and closing, and ensure that the pliers head can be opened without interference when the push plate is squeezed downward. After opening, the spring installed on the baffle can provide pulling force, and when clamping is not needed, the push plate is pulled down to press the chuck to open, so as to ensure that the pliers head is in an open state when not in use. Such a design is convenient for driving the pliers head to reset.

The connecting plate of the moving component moves along the placement cavity in the placement cavity, and the connecting plate is pushed by the push rod, and the connecting plate is connected to the push plate. When installing the pliers head, when the mounting block of the rotating pliers head is connected to the inner wall of the hand-held rod, the push plate gradually contacts the connecting plate until the clamping plate corresponds to the through groove, and the clamping plate passes through the through groove, and continues to rotate after passing through the through groove, and the clamping column is transferred from the through groove to the clamping groove. Since the clamping groove corresponds to the clamping column, and the diameter of the clamping groove is smaller than the clamping plate, the clamping plate is restricted to the other side of the connecting plate, completing the connection between the push plate and the connecting plate. Such a design facilitates connection with the push plate.
