Description

Technical Field

[0001] The invention relates to the field of medical auxiliary materials, and in particular to a processing technology for a noise reduction tube of an ultrasonic hemostatic knife. Background Art

[0002] The ultrasonic hemostatic knife system (also known as ultrasonic scalpel) is a surgical instrument that uses high-speed vibration to achieve cutting and separation of biological bodies. The ultrasonic hemostatic knife system consists of three main components: ultrasonic excitation power supply (host generator), drive handle (including ultrasonic transducer) and ultrasonic hemostatic knife (instrument). The main function of the ultrasonic excitation power supply is to generate high-frequency and controllable electrical power, and during the tissue cutting process, the energy can be adjusted according to the coagulation speed and cutting speed. The function of the drive handle is to convert high-frequency electrical energy into ultrasonic vibration (mechanical) energy.

[0003] The ultrasonic hemostatic knife includes a handle, a knife rod and a knife head. The handle and the knife head are respectively connected to the two ends of the knife rod. The driving handle transmits ultrasonic vibration energy to the knife rod, which will generate noise and excess vibration in the radial direction, which will not only affect the operator's usage status, but also affect the operator's operating precision.

[0004] The existing solution is to install a noise reduction tube on the outer surface of the cutter bar to reduce noise and reduce the unnecessary vibration in the radial direction. The existing noise reduction tube is cut from a purchased roll of hose. The specific steps are as follows: First, cut the hose to the appropriate length according to the length of the cutter bar; Then, a fitting groove is cut in the radial direction of the hose, and the length of the fitting groove is the same as the length of the hose.

[0005] The above-mentioned noise reduction pipe made of a hose has multiple problems: First, the production process of the hose is extrusion. There is no mold support when the tube body is extruded and shaped, and the tube wall is thin. The size of the extruded hose after cooling and shrinkage is difficult to control, and the resulting hose is uneven in size, which is quite different from the target size. Second, the purchased hoses are all packaged in rolls, so the cut hoses have a certain curvature. The noise reduction tubes made from the curved hoses also have a certain curvature. When they are assembled on the knife rod, the fit with the knife rod is poor, which ultimately leads to poor noise reduction and vibration reduction effects of the noise reduction tubes.

[0006] In order to achieve the best noise reduction and vibration reduction effect of the noise reduction tube, the gap between the noise reduction tube and the tool rod needs to be controlled within 0.1mm. However, the existing noise reduction tube has large deformation and dimensional tolerance deviations and cannot achieve the expected effect. Summary of the invention

[0007] The purpose of the present invention is to propose a processing technology for the noise reduction tube of an ultrasonic hemostatic knife based on the existing noise reduction tube and the demand for the noise reduction tube suitable for an ultrasonic hemostatic knife to reduce noise and weaken unnecessary vibration in the radial direction.

[0008] A processing technology for a noise reduction tube of an ultrasonic hemostatic knife, characterized in that the noise reduction tube material is deformable at high temperature, and a noise reduction tube shaping device is used to make the noise reduction tube reach the use size standard, the shaping device includes a baking tray for holding unshaped noise reduction tubes (referring to hoses cut according to the length of the knife rod), a standard rod capable of sleeve-mounting the unshaped noise reduction tubes and shaping them, and a heating device for heating the unshaped noise reduction tubes, the standard rod is arranged on the baking tray, and the standard rod is provided with a cutting groove; In order to make the noise reduction pipe reach the standard size for use, the unformed noise reduction pipe is processed as follows: (1) Sleeve the unshaped noise reduction tube onto the standard rod; (2) using a heating device to heat the unshaped noise reduction tube to shrink the unshaped noise reduction tube; (3) Stop heating and wait for the noise reduction pipe to cool down and set; (4) Using a cutting tool to cut the noise reduction pipe after cooling and shaping along the cutting groove to obtain a finished noise reduction pipe.

[0009] By adopting the above-mentioned noise reduction pipe processing technology, the high-temperature deformable characteristics of the noise reduction pipe material are utilized to make it deform and shrink in a high-temperature environment so that it can meet the use size standard, and it can also be quickly cut and installed. Only with a simple structure and process, the problem that the existing processing technology cannot produce a noise reduction pipe that meets the use requirements is solved, and the effect of reducing noise and reducing the redundant vibration in the radial direction of the noise reduction pipe is greatly improved.

[0010] Furthermore, the standard rod is detachably mounted on the baking tray.

[0011] Furthermore, the baking tray is provided with mounting holes distributed in an array, wherein the mounting holes are provided in n×m numbers, "n" means that the mounting holes are provided in n rows, "m" means that the mounting holes are provided in m columns, and the standard rods are also provided in n×m numbers. Multiple unformed noise reduction tubes can be heated and shaped at one time, thereby improving processing efficiency.

[0012] In order to reduce the volume of the shaping device, the gap between the mounting holes is smaller. Then the standard rod set in the middle will be difficult to fit the unshaped noise reduction tube due to the small operating gap. Therefore, the standard rod is detachably set in the mounting hole, which is not only convenient for fitting the unshaped noise reduction tube, but also convenient for cutting the finished noise reduction tube.

[0013] Furthermore, the standard rod includes a molding body and an installation head, the molding body is fixedly connected to the installation head, the cutting groove runs through the molding body and the installation head, and the cutting groove arranged on the molding body and the cutting groove arranged on the installation head are located in the same plane.

[0014] Furthermore, the diameter of the mounting head is larger than the diameter of the shaping body, the mounting head is arranged at one end for connecting with the baking tray, the diameter of the mounting head corresponds to the diameter of the mounting hole, and the diameter of the shaping body is to reach the inner diameter of the standard noise reduction pipe.

[0015] Furthermore, the mounting holes on the baking trays have the same size.

[0016] Since there are a large number of mounting holes, if different sizes are set, the operator needs to match them one by one, which takes a lot of time. Therefore, the mounting holes are set to the same size, and the standard rod can be connected to any mounting hole, which improves the processing efficiency.

[0017] The unshaped noise reduction tube is a long tubular structure with a soft texture and a certain curvature. Therefore, when the operator generally sets the unshaped noise reduction tube on the shaped body, he will hold one end of the unshaped noise reduction tube with one hand and change the holding position of the other hand according to the moving position of the unshaped noise reduction tube when setting it.

[0018] The position of the unshaped noise reduction tube finally mounted on the shaped body is not fixed, so a cutting groove running through the shaped body and the mounting head needs to be provided to ensure that the unshaped noise reduction tube can be cut at any position of the shaped body after being tensioned on the shaped body after heating and shaping.

[0019] The diameter of the installation head is larger than the diameter of the finalized main body, which limits the downward movement limit position of the noise reduction pipe, facilitates the installation of the unformed noise reduction pipe, and improves work efficiency.

[0020] Furthermore, the axis centerline of the mounting hole is in a vertical direction, and the axis centerlines of the standard rods disposed in the mounting hole coincide with each other, and the axis centerline of the standard rods disposed in the mounting hole is in a vertical direction.

[0021] Furthermore, the baking tray is provided with a handle, and two handles are provided and are respectively located on two sides of the baking tray.

[0022] Furthermore, the heating device adopts an oven, which can make the noise reduction tube placed inside the oven be heated evenly, and has a large controllable temperature range, fast heating, and a simple structure, thereby ensuring its work quality while also ensuring its work efficiency.

[0023] Furthermore, the cutting tool is a knife.

[0024] Furthermore, based on the above-mentioned shaping device structure, the specific processing technology includes the following steps: (1) respectively sleeve n×m unshaped noise reduction tubes on n×m standard rods; (2) placing the n×m standard rods sleeved with unshaped noise reduction tubes in the n×m mounting holes respectively; (3) The operator holds the handle and places the baking tray containing the unformed noise reduction tube into the oven, and uses the oven to heat the unformed noise reduction tube, so that the unformed noise reduction tube shrinks and is tensioned on the standard rod; (4) Stop heating and wait for the heated noise reduction tube to cool down and set; (5) Using a tool to cut the noise reduction pipe after cooling and shaping along the cutting groove, finally obtaining a noise reduction pipe finished product with a size that meets the standard for use.

[0025] The beneficial effects of the present invention are as follows: the processing technology for the noise reduction tube of the ultrasonic hemostatic knife disclosed in the present application utilizes the high-temperature deformable characteristic of the noise reduction tube material, and cooperates with a shaping device to enable it to deform and shrink in a high-temperature environment. With a simple processing technology, the noise reduction tube that originally does not meet the use size standards is processed into a noise reduction tube that meets the use size standards, which greatly improves the effect of the noise reduction tube in reducing noise and weakening unnecessary vibration in the radial direction. Through the array-distributed mounting holes and standard rods, multiple noise reduction tubes can be processed at the same time, greatly improving production efficiency.

In order to more clearly understand the technical means of the present invention, it can be implemented in accordance with the contents of the specification.

DETAILED DESCRIPTION

[0028] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0029] The processing technology of the present invention will be further described in conjunction with the accompanying drawings.

[0030] like Figure 1 and Figure 2 As shown, the shaping device using the processing technology described in this embodiment includes an oven, a baking tray 101 and a standard rod 104. The baking tray 101 is provided with mounting holes 102 distributed in an array. The mounting holes 102 are provided with 25×8, "25" means that the mounting holes 102 are provided with 25 rows, and "8" means that the mounting holes 102 are provided with 8 columns. There are 200 mounting holes 102 in total, and the size of each mounting hole 102 is consistent. Since there are a large number of mounting holes 102, if different sizes are set, the operator needs to match them one by one, which takes a lot of time. Therefore, the mounting holes 102 are set to the same size, and the standard rod 104 can be connected to any mounting hole 102.

[0031] The upper end surface of the baking tray 101 is provided with a fixedly connected handle 103, and two handles 103 are provided and are respectively located on the left and right sides of the baking tray 101, and the positions are symmetrical about the center point of the baking tray 101.

[0032] The standard rod 104 is detachably arranged in the mounting hole 102, which is convenient for the operator to take. In order to reduce the volume of the shaping device, the gap between the mounting holes 102 is small. If the standard rod 104 is not detachable, then the standard rod 104 arranged in the middle will be difficult to set the unshaped noise reduction pipe due to the small operating gap. Therefore, the standard rod 104 is detachably arranged in the mounting hole 102, which is not only convenient for setting the unshaped noise reduction pipe, but also convenient for cutting the finished noise reduction pipe.

[0033] like Figure 3 , Figure 4 As shown, the standard rod 104 includes a shaping body 105 and a mounting head 106. The mounting head 106 is arranged at one end of the shaping body 105, and the diameter of the mounting head 106 is larger than the diameter of the shaping body 105. The diameter of the shaping body 105 is to achieve the inner diameter of the standard noise reduction pipe.

[0034] The diameter of the mounting head 106 corresponds to the diameter of the mounting hole 102 .

[0035] The mounting hole 102 is vertically arranged, and the standard rod 104 is also vertically arranged when arranged in the mounting hole 102 .

[0036] like Figure 5 , Figure 6 and Figure 7 As shown, a cutting groove 107 is provided on the molding body 105 and the mounting head 106. The cutting grooves 107 on the molding body 105 and the mounting head 106 are located in the same plane. The cutting groove 107 is located on one side of the standard rod 104 and passes through the upper and lower end surfaces of the standard rod 104.

[0037] The depth of the cutting groove 107 on the setting body 105 is L1, the radius of the setting body 105 is R1, and the radius of the mounting head 106 is R2. L1<R1, R1<R2, The groove depth L2 of the cutting groove 107 on the molding body 105 is L2=R2-R1+L1.

[0038] The processing steps proposed based on the above-mentioned shaping device are as follows: (1) 200 unshaped noise reduction tubes are respectively placed on 200 standard rods 104; (2) 200 standard rods 104 with unshaped noise reduction tubes are respectively arranged in 200 mounting holes 102 of the baking tray 101; (3) The operator holds the handle 103 and places the baking tray 101 containing the unshaped noise reduction tube into the oven, and uses the oven to heat the unshaped noise reduction tube, so that the unshaped noise reduction tube shrinks and is stretched on the standard rod 104; (4) Stop heating and wait for the heated noise reduction tube to cool down and set; (5) Use a tool to cut the noise reduction pipe after cooling and shaping along the cutting groove 107, and finally obtain a noise reduction pipe finished product with a size that meets the standard for use.

[0039] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
