Description

TECHNICAL FIELD

[0001] The utility model relates to the field of medical supplies especially to a shaping device for the noise reduction pipe of an ultrasonic hemostatic knife. BACKGROUND

[0002] The ultrasonic hemostatic knife system (also called ultrasonic surgical knife) is a surgical instrument for cutting and separating biological tissues through high-speed vibration. The ultrasonic hemostatic knife system comprises three main components: an ultrasonic excitation power supply (main generator), a driving handle (containing an ultrasonic transducer) and an ultrasonic hemostatic knife (instrument). The main function of the ultrasonic excitation power supply is to generate high-frequency and controllable electric power, and during the process of tissue cutting, the power can be adjusted according to the coagulation speed and cutting speed. The function of the driving handle is to convert high-frequency electric energy into ultrasonic vibration (mechanical) energy.

[0003] The ultrasonic hemostatic knife comprises a handle, a knife rod and a knife head, the handle and the knife head are connected to the two ends of the knife rod respectively, and the driving handle transmits ultrasonic vibration energy to the knife rod, which will generate noise and excessive vibration in the radial direction, affecting not only the use of the operator but also the operation accuracy of the operator.

[0004] The existing solution is to provide a noise reduction pipe outside the knife rod to reduce noise and weaken the excessive vibration in the radial direction. The existing noise reduction pipe is cut from a purchased soft tube, and the specific steps are as follows:

[0005] Firstly, the soft tube is cut to a length suitable for the length of the knife rod.

[0006] Then, a fitting groove is cut in the radial direction of the soft tube, and the length of the fitting groove is the same as that of the soft tube.

[0007] The above-mentioned noise reduction pipe made of a soft tube has the following problems:

[0008] Firstly, the production process of the soft tube is extrusion, and the tube body is not supported by a mold during the extrusion and shaping, and the tube wall is relatively thin, so the size of the extruded soft tube is difficult to control after cooling and shrinking, and the final soft tube has uneven size and large difference from the target size.

[0009] Secondly, the purchased soft tube is packaged in a roll, so the cut soft tube has a certain curvature, and the noise reduction pipe made of the soft tube with curvature also has a certain curvature, which has poor fit with the knife rod, and finally leads to poor noise reduction and vibration reduction effect of the noise reduction pipe.

[0010] In order to achieve good noise reduction and vibration reduction effect of the noise reduction pipe, the gap between the noise reduction pipe and the knife rod needs to be controlled within 0.1mm, but the existing noise reduction pipe has large deformation and size tolerance deviation, which cannot achieve the expected effect. INVENTION CONTENTS

[0011] The utility model discloses a purpose lies in on the basis of the existing noise reduction pipe, based on the demand of the noise reduction pipe suitable for ultrasonic hemostatic knife can reduce noise and weaken the excess vibration of radial direction, build and form a kind of for ultrasonic hemostatic knife noise reduction pipe's shaping device.

A plurality of unshaped noise reduction pipes can be heated and shaped at one time, improving the processing efficiency. In order to reduce the volume of the shaping device, the gap between the mounting holes is small, so the standard stick arranged in the middle is difficult to set the unshaped noise reduction pipe due to the small operation gap. Therefore, the standard stick is detachably arranged in the mounting hole, which not only facilitates the setting of the unshaped noise reduction pipe, but also facilitates the cutting of the noise reduction pipe product.

[0016] Further, the standard stick includes a shaping body and a mounting head, the shaping body is fixedly connected with the mounting head, the cutting groove penetrates through the shaping body and the mounting head, and the cutting groove arranged on the shaping body is located in the same plane as the cutting groove arranged on the mounting head.

[0018] Further, the mounting holes on the baking tray are of the same size.

[0019] Since the number of mounting holes is large, if different sizes are set, the operator needs to correspond one by one, which needs to consume a lot of time, so the mounting holes are set to the same size, the standard rod can be connected with any mounting hole, and the processing efficiency is high.

[0020] The unshaped noise reduction pipe is a long strip-shaped tubular structure, and has soft texture and certain arc, so when the unshaped noise reduction pipe is sleeved on the shaping body by a general operator, one hand holds one end of the unshaped noise reduction pipe, and the other hand changes the holding position according to the moving position of the unshaped noise reduction pipe during sleeving.

[0021] The position of the unshaped noise reduction pipe finally sleeved on the shaping body is not fixed, so the cutting groove penetrating through the shaping body and the mounting head is arranged to ensure that the unshaped noise reduction pipe can be cut after being tensioned at any position of the shaping body after heating and shaping.

[0022] The diameter of the mounting head is greater than that of the shaping body, which limits the lower limit position of the noise reduction pipe, facilitates sleeving of the unshaped noise reduction pipe, and improves work efficiency.

[0023] Further, the axis of the mounting hole is in a vertical direction, and the axis of the standard rod arranged in the mounting hole is coincident, and the axis of the standard rod arranged in the mounting hole is in a vertical direction.

[0024] Further, the baking tray is provided with a handle, and the handle is provided with two and located on two sides of the baking tray.

[0025] Further, the heating equipment adopts an oven, the noise reduction pipe placed in the oven can be heated uniformly, the controllable temperature range is large, the temperature rises quickly, the structure is simple, the working quality is ensured, and the working efficiency is also ensured.

[0026] Further, the shaping device further comprises a cutter for cutting the cooled and shaped noise reduction pipe along the cutting groove.
