Detailed Description

The following provides a detailed description of the embodiments of the present invention with reference to the examples.

A bipolar electric coagulation forceps for stopping bleeding of a neuroendoscopy operation is shown in figures 1-6 and comprises an electrode holder 1, a kneading part, a forceps column 3, a forceps tip 4 and a clamping mechanism. The kneading part comprises two holding rods 2 which are oppositely arranged, and the tail parts of the two holding rods 2 are respectively connected with the anode and the cathode of the electrode holder 1; the two holding rods 2 are connected with two forceps tips 4 through the forceps column 3, the two forceps tips 4 are respectively in a separated shape with the tail ends connected with the anode and the cathode, and the front ends of the two forceps tips 4 can be driven by the clamping mechanism to be in contact power supply to realize hemostasis.

Two chambers, namely a positive electrode chamber and a negative electrode chamber, are arranged in the electrode holder 1 side by side; and each cavity is internally provided with a wiring terminal and an electric wire 5 connected with the wiring terminal, and the electric wire 5 is connected with a power supply through a plug or other conversion devices. The two holding rods 2 are respectively inserted into the positive electrode cavity and the negative electrode cavity and fixed, so that current conduction is realized.

The holding rod 2 is a force application kneading component, and the holding rod 2 is a deformable rod which deforms after being stressed to drive the clamping mechanism to act. The shape of the holding rod 2 can be an arc-shaped rod as shown in fig. 1 and fig. 2, and the two arc-shaped rods are enclosed to form a spindle shape; or in a fold line shape, and the two fold line-shaped holding rods 2 enclose to form a quadrangle. The grip 2 may be linear in side view or may be bent as shown in fig. 3, and is generally preferably bent to facilitate grasping and application of force.

The outside of the holding rod 2 is provided with an insulating sleeve 11, and a plurality of anti-slip lines are stamped or integrally formed on the insulating sleeve 11, so that force is applied by a doctor conveniently.

As for the way of conducting the electric current by the holding rod 2, there are two ways, one of which is that the holding rod 2 itself is a metal rod with good conductivity, the exterior of the metal rod is coated with insulating paint, and then sleeved with an insulating sleeve 11, and the electric transmission is realized by the contact between the metal rod and the connecting terminal; secondly, the holding rod 2 is an insulating rod, such as a plastic rod, a rubber rod or the like, an electric conducting wire penetrates through the insulating rod along the axial direction, one end of the holding rod 2, which is inserted into the electrode base 1, is provided with a conducting strip connected with the electric conducting wire, and electricity transmission is realized through the contact of the conducting strip and a connecting terminal.

As shown in fig. 6, in order to ensure that the two handles 2 can be rapidly rebounded without external force, a compression spring 10 is preferably fixedly disposed between the two handles 2. A set of relatively convex mounting tables are correspondingly arranged on the two holding rods 2, the two ends of the compression spring 10 are inserted into the mounting tables and are fixed, and meanwhile, the two relatively arranged mounting tables can also play a certain limiting role. Due to the existence of the compression spring 10, a certain supporting force exists between the holding rods 2, the holding rods 2 are not pinched and do not deform, and the fault power connection is avoided; after the force is released, the grip 2 is quickly restored by the resilience of the compression spring 10.

As shown in fig. 5, the forceps column 3 is a straight column, and two ends of the forceps column 3 are respectively electrically connected with the two holding rods 2 and the two forceps tips 4, so as to supply power to the forceps tips 4. The inside of tweezers post 3 is provided with looks mutual separation and insulating anodal post 12 and negative pole post 13, and anodal holding rod 2 is connected to the one end of anodal post 12, and anodal tweezers point 4 is connected to the other end, and negative pole holding rod 2 is connected to the one end of negative pole post 13, and negative pole tweezers point 4 is connected to the other end, realizes that anodal, negative pole supply power simultaneously. The exterior of the tweezer column 3 is coated with an insulating sleeve 11.

The two forceps tips 4 are terminal working parts of the electric coagulation forceps. The tail parts of the two forceps tips 4 are separated and respectively connected with the positive pole column 12 and the negative pole column 13 in a bendable manner; under the non-working state, the front ends of the forceps tips 4 are splayed and separated, and the front ends of the forceps tips 4 are closed and contacted under the action of external force. The front end of the forceps tip 4 is in a sharp-pointed shape, so that accurate hemostasis can be performed on the cerebral microvasculature conveniently.

As shown in fig. 1 to 4, the clamping mechanism includes a V-shaped clamping piece 6, a pushing rod 7, a fixed pushing ring 8 and a pressing ring 9. Two ends of the V-shaped clamping piece 6 are respectively fixed at the rear ends of the two holding rods 2, the conical tip part of the V-shaped clamping piece 6 points to the forceps tips 4, and the conical tip part of the V-shaped clamping piece 6 is fixedly connected with the pushing rod 7; the front end of the pushing rod 7 is fixedly connected with a fixed pushing ring 8, and the fixed pushing ring 8 is sleeved at the tail parts of the two conical tips. When a doctor kneads the holding rod 2, the holding rod 2 deforms to drive the V-shaped clamping piece 6 to deform and stretch forwards, the pushing rod 7 moves forwards along with the V-shaped clamping piece 6 to drive the fixed pushing ring 8 to move towards the front end of the conical tip, and the front end of the conical tip is folded after the conical tip is stressed, so that power on is achieved.

In order to ensure that the pushing rod 7 is pushed forwards horizontally, a pressing ring 9 is further arranged outside the forceps column 3. The pressing ring 9 can be in two forms, namely, the pressing ring 9 is sleeved outside the tweezer column 3, the inner diameter of the pressing ring 9 is in clearance fit with the outer diameter of the tweezer column 3, and the outer edge of the pressing ring 9 is welded on the push rod 7; and in the second form, the pressing ring 9 is welded or integrally formed outside the tweezer column 3, one side of the pressing ring 9 is provided with a through hole for the passing of the tweezer column 3, and the through hole is in sliding fit with the tweezer column 3.

The utility model discloses a working process does:

when hemostasis operation is carried out, a doctor holds the electric coagulation forceps to send the electric coagulation forceps to a blood vessel, forcibly kneads the holding rod, drives the push rod to axially extend forwards after the holding rod is deformed, fixes the push ring to be pressed forwards to the middle part of the forceps tip, enables the front ends of the forceps tip to be closed and contacted, and is electrified to realize hemostasis; after hemostasis, the fixed push ring can be driven to rapidly retract to the tail part of the forceps tip by loosening the hand, the front end of the forceps tip is separated, and the electrification is stopped.

The electric coagulation forceps are in a columnar shape when searching for bleeding points, so that the electric coagulation forceps can conveniently pass through the working channel, and other instruments are not influenced and are used at the same time; the folding and separating processes of the forceps tips are rapid, the opening and the closing are small, the operation is simple and sensitive, and surrounding tissues are not easy to damage.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and additions can be made without departing from the principles of the present invention, and these improvements and additions should also be regarded as the protection scope of the present invention.
