Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a shaping device for the forceps-type blade of an ultrasonic cutting hemostatic knife. Background Technology

[0002] The ultrasonic cutting hemostat forceps-type tip is a surgical tool that uses high-frequency ultrasonic vibrations to achieve precise cutting and rapid hemostasis of tissue. It is often used in minimally invasive surgery or complex tissue treatment, and can reduce intraoperative bleeding, reduce the risk of thermal damage, and improve surgical safety.

[0003] Due to the scissor-like structure of the clamp-type ultrasonic scalpel, the tissue pad and amplitude bar should form a straight line after closure, without gaps, to achieve better cutting and rapid hemostasis. The closure effect is related to the clamping assembly of the clamp-type scalpel head. When the clamping assembly is slightly deformed due to processing or assembly, the finished product will have gaps, poor closure force, and poor gripping force.

[0004] Therefore, it is necessary to design a shaping device for the clamp-type blade of an ultrasonic cutting hemostatic knife to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a shaping device for the clamp-type cutting tip of an ultrasonic cutting hemostatic scalpel. This device can improve the closing gap, closing force, and gripping force of the clamp-type cutting tip by slightly shaping the clamping components. This increases the yield of clamp-type cutting tip production and reduces material loss.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A shaping device for the tip of an ultrasonic cutting hemostatic scalpel includes a base plate, a hand press mounted on the upper end of the base plate, a contouring base and a fitting block on the upper end of the base plate, contouring grooves on adjacent sides of the contouring base and the fitting block, both contouring grooves being X-shaped, an assembly head on the hand press, a pressure head on the assembly head, and the contouring base and the base plate connected by two connecting components.

[0008] Preferably, the contour base is provided with two first assembly holes, and the fitting block is provided with two third assembly holes. The inner wall of each first assembly hole and third assembly hole is provided with a threaded layer, and each pair of mating first assembly holes and third assembly holes is threadedly connected with an assembly bolt.

The gear meshes with the toothed ridges. Two sliding rods are fixedly connected to the lower end of the horizontal plate. Two sliding grooves are provided at the upper end of the housing. The lower ends of the two sliding rods extend into the corresponding sliding grooves.

[0012] Preferably, the slide bar located on the left side has a threaded layer and is threadedly connected to a stop nut.

[0013] Preferably, the outer wall of the rhomboid limiting device slides and fits against the inner wall of the through hole, and the height of the rhomboid limiting device is the same as the thickness of the base plate.

[0017] Compared with existing technologies, the advantages of this device are:

[0018] 1. Compared with the existing technology, this device, through the contouring base and the contouring groove design of the fitting block, can accurately adapt to the structure of the clamp-type cutter head clamping component, so that the cutter head is subjected to uniform force during the shaping process, effectively improving the problems of poor closing gap, poor closing force and gripping force caused by the deformation of the clamping component, and improving the shaping effect and the yield of finished cutter head.

[0019] 2. Compared with the existing technology, the device uses screw connection to fix the contour base and the bonding block, as well as the contour base and the base plate. This connection method is not only structurally stable and easy to install and disassemble, but also ensures the relative position stability of each component during the shaping process, ensuring the reliability and consistency of the shaping operation.

[0020] 3. Compared with existing technologies, the design of the hand press makes it easier for operators to apply pressure. Through the meshing structure of the adjustable wrench and gears and teeth, precise control of the pressing head's downward pressing process can be achieved. At the same time, the setting of the stop nut can accurately control the pressing stroke, avoid over-shaping, improve the controllability and safety of the shaping operation, reduce material loss, and can also perform multiple shaping processes by rotating the stop nut.
