Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a surgical muscle retraction device. Background Technology

[0002] Currently, in surgical procedures, wounds need to be pulled and fixed before surgery can be performed. Existing surgical retractors do not have a fixing device and can only be manually pulled by the surgeon using instruments. This results in inaccurate pulling of the retractors during the operation, and prolonged hand-holding can cause shaking, affecting the surgeon's operation.

[0003] In the prior art, by adding a base to one end of the hook and fixing the base to one side of the operating table, the patient's tissue can be pulled by adjusting the height and angle, thereby stably pulling and fixing the patient's incision tissue.

[0004] However, in the existing technology, when cleaning and disinfecting the hook, it is necessary to disinfect the entire hook and base, which makes the operation complicated and cumbersome and is not conducive to rapid disinfection. Summary of the Invention

[0005] The purpose of this invention is to provide a surgical muscle retraction device, which aims to solve the technical problem in the prior art that the entire retractor and base need to be disinfected when cleaning and disinfecting the retractor, resulting in complicated and cumbersome operation and hindering rapid disinfection.

[0006] To achieve the above objectives, the present invention employs a surgical muscle retraction device, comprising a hook and a disassembly / assembly mechanism. The disassembly / assembly mechanism includes a housing, a spring, a magnetic plate, and steel balls. One end of the hook has a groove and is embedded inside the housing. The magnetic plate is disposed inside the housing. Both ends of the spring are fixedly connected to the magnetic plate and the housing, respectively, and are located between the housing and the magnetic plate. The number of steel balls is multiple, with each steel ball disposed on the upper end of the magnetic plate and on the outer wall of the hook.

[0007] The housing includes a chamber, a connecting shell, and a bottom shell. The spring, the magnetic plate, and the steel ball are respectively disposed inside the chamber. The connecting shell is fixedly connected to the chamber and is sleeved on the outer wall of the connecting shell. The bottom shell is fixedly connected to the connecting shell and is located at the lower end of the connecting shell. One end of the chamber is embedded inside the bottom shell.

[0008] The disassembly and assembly mechanism further includes a magnetic suction component, which is fixedly connected to the bottom shell and located at one end of the bottom shell.

[0009] The magnetic attraction assembly includes a housing, a magnetic core, a PCB control board, and an energized coil. The housing is fixedly connected to the bottom shell and located at one end of the bottom shell. The magnetic core is disposed inside the housing. The energized coil is disposed inside the housing and is sleeved on the outer wall of the magnetic core. The PCB control board is fixedly connected to the housing and located inside the housing, and is electrically connected to the energized coil.

[0010] The magnetic component also includes a Bluetooth module, which is electrically connected to the PCB control board and located on one side of the PCB control board.

[0011] The surgical muscle retraction device further includes a base connection assembly, which is disposed at both ends of the bottom shell.

[0012] The base connection assembly includes an insert, a support column, a slider, and an electromagnet. There are two support columns, each of which is fixedly connected to the bottom shell and located at both ends of the bottom shell. The two ends of the insert are rotatably connected to the corresponding support column. The slider is fixedly connected to the insert and located on one side of the insert. The electromagnet is fixedly connected to the insert and located on one side of the insert.

[0013] The base connection assembly further includes two rubber rings, each of which is disposed on the outer wall of the corresponding support column and is located between the support column and the insert.

[0014] This invention discloses a surgical muscle retraction device. The device is fixed to the upper end of a suitable support frame via a housing. The sterilized end of a retractor is inserted into the housing. After insertion, the retractor pushes the steel balls and magnetic plate, thereby compressing the spring. The retractor can be inserted into the center of multiple steel balls, each steel ball's outer wall embedded in a slot. Multiple steel balls engage the retractor. At the moment the steel balls engage the retractor, the spring's rebound force pushes the magnetic plate back to its original position, achieving the purpose of engaging the retractor. When disassembling the retractor, a strong magnetic force is used at the end of the housing to attract the spring and magnetic plate, loosening the magnetic plate and steel balls, allowing the retractor to be pulled out. This structure allows for easy disassembly and assembly of the retractor, enabling rapid cleaning, sterilization, and replacement. Furthermore, when placed on the support structure, it can be handled without manual intervention. Attached Figure Description

Detailed Implementation

[0021] The first embodiment of this application is as follows:

[0022] Please see Figure 1 ,in Figure 1 This is a cross-sectional view of the internal structure of the first embodiment of the present invention.

[0023] The present invention provides a surgical muscle retraction device, comprising a hook 101 and a disassembly and assembly mechanism. The disassembly and assembly mechanism includes a housing 109, a spring 105, a magnetic plate 106, a steel ball 107, and a magnetic attraction assembly. The housing 109 includes a chamber 102, a connecting shell 103, and a bottom shell 104. The magnetic attraction assembly includes the housing 109, a magnetic core 110, a PCB control board 111, a power-conducting coil 112, and a Bluetooth module 113.

[0024] In this specific embodiment, the housing 109 is composed of the chamber 102, the connecting shell 103 and the bottom shell 104, and the spring 105, the magnetic plate 106 and the steel ball 107 are placed therein. The hook 101 is fixed by the steel ball 107 clamping the hook 101.

[0025] The hook 101 has a slot 108 at one end, and one end of the hook 101 is embedded inside the housing 109. The magnetic plate 106 is disposed inside the housing 109. The two ends of the spring 105 are fixedly connected to the magnetic plate 106 and the housing 109 respectively, and are located between the housing 109 and the magnetic plate 106. There are multiple steel balls 107, each steel ball 107 is disposed at the upper end of the magnetic plate 106, and each steel ball 107 is located on the outer wall of the hook 101. The housing 109 is fixed to the upper end of the matching support frame, and the sterilized tail end of the hook 101 is inserted into the housing 109. After the hook 101 is inserted into the housing 109, the hook 101 engages with the magnetic plate 106. The steel balls 107 and the magnetic plate 106 are pushed together, thereby squeezing the spring 105. The hook 101 can be inserted into the center of multiple steel balls 107. The outer wall of each steel ball 107 is embedded in the inside of the slot 108. Multiple steel balls 107 complete the engagement of the hook 101. At the moment when the steel balls 107 engage the hook 101, the rebound force of the spring 105 pushes the magnetic plate 106 to reset, thus achieving the purpose of engaging the hook 101. When disassembling the hook 101, a strong magnetic force is used at the end of the housing 109 to attract the spring 105 and the magnetic plate 106, thereby loosening the magnetic plate 106 and the steel balls 107, so that the hook 101 can be pulled out.

[0026] Secondly, the spring 105, the magnetic plate 106, and the steel ball 107 are respectively disposed inside the chamber 102. The connecting shell 103 is fixedly connected to the chamber 102 and sleeved on the outer wall of the connecting shell 103. The bottom shell 104 is fixedly connected to the connecting shell 103 and located at the lower end of the connecting shell 103. One end of the chamber 102 is embedded inside the bottom shell 104. The chamber 102 places the spring 105, the magnetic plate 106, and the steel ball 107, while the connecting shell 103 provides support. The connecting shell 103 also supports the bottom shell 104.

[0027] Meanwhile, the magnetic suction assembly is fixedly connected to the bottom shell 104 and located at one end of the bottom shell 104. The housing 109 is fixedly connected to the bottom shell 104 and located at one end of the bottom shell 104. The magnetic core 110 is disposed inside the housing 109. The energized coil 112 is disposed inside the housing 109 and is sleeved on the outer wall of the magnetic core 110. The PCB control board 111 is fixedly connected to the housing 109 and located inside the housing 109. The PCB control board 111 is electrically connected to the energized coil 112. When the hook 101 is disassembled, the PCB control board 111 controls the energized coil 112 to be energized, so that the magnetic core 110 has electromagnetic force. The electromagnetic force magnetically attracts the magnetic plate 106 and the spring 105, causing the steel ball 107 to loosen.

[0028] In addition, the Bluetooth module 113 is electrically connected to the PCB control board 111 and is located on one side of the PCB control board 111. Through the adaptation of the Bluetooth module 113 and the PCB control board 111, remote control of the energized coil 112 can be realized, enabling integrated unified control.

[0029] When using a surgical muscle retractor device according to this embodiment, the housing 109 is fixed to the upper end of a suitable support frame, and the sterilized tail end of the hook 101 is inserted into the housing 109. After the hook 101 is inserted into the housing 109, the hook 101 pushes the steel ball 107 and the magnetic plate 106, thereby squeezing the spring 105. The hook 101 can be inserted into the center of multiple steel balls 107, and the outer wall of each steel ball 107 is embedded in the slot 108. Multiple steel balls 107 complete the engagement of the hook 101. At the moment when the steel ball 107 engages the hook 101, the rebound force of the spring 105 pushes the magnetic plate 106 to reset, achieving the purpose of engaging the hook 101. When disassembling the hook 101, the housing 109 is... The end of 09 uses strong magnetic force to attract the spring 105 and the magnetic plate 106, thereby loosening the magnetic plate 106 and the steel ball 107, allowing the hook 101 to be pulled out. The housing 102 holds the spring 105, the magnetic plate 106, and the steel ball 107, while the connecting shell 103 provides support. The connecting shell 103 supports the bottom shell 104. When disassembling the hook 101, the PCB control board 111 controls the energizing coil 112 to be energized, giving the magnetic core 110 electromagnetic force. This electromagnetic force magnetically attracts the magnetic plate 106 and the spring 105, loosening the steel ball 107. Through the adaptation of the Bluetooth module 113 and the PCB control board 111, remote control of the energizing coil 112 can be achieved, enabling integrated unified control.

[0030] The second embodiment of this application is as follows:

[0031] Based on the first embodiment, please refer to Figure 2 ,in Figure 2 This is a cross-sectional view of the internal structure of the second embodiment of the present invention.

[0032] The present invention provides a surgical muscle retraction device, which further includes a base connection assembly, the base connection assembly including a block 201, a support 202, a slider 203, an electromagnet 204, and a rubber ring 205.

[0033] In this specific embodiment, the insert 201 is adapted to the support column 202 to achieve angle control of the hook 101, thereby completing the purpose of traction and pressing during the operation. The electromagnet 204 fixes the support column 202 to prevent it from rotating during use.

[0034] The system comprises two support pillars 202, each fixedly connected to the base shell 104 and located at both ends of the base shell 104. The two ends of each insert block 201 are rotatably connected to the corresponding support pillar 202. A slider 203 is fixedly connected to the insert block 201 and located on one side of the insert block 201. An electromagnet 204 is fixedly connected to the insert block 201 and located on one side of the insert block 201. The connection between the support pillar 202 and the insert block 201 allows for adjustment of the angle of the hook 101. After adjustment to a suitable angle, the electromagnet 204 is activated to magnetically fix the support pillar 202, preventing rotation. The slider 203 connects to the support structure, facilitating easy assembly and disassembly of the support.

[0035] Secondly, there are two rubber rings 205. Each rubber ring 205 is respectively disposed on the outer wall of the corresponding support 202 and located between the support 202 and the insert 201. By using the two rubber rings 205 on the outer walls of the two supports 202, the support 202 can form a certain resistance, which can slow down the easy rotation of the support 202 and achieve the purpose of strengthening stability.

[0036] When using a surgical muscle retraction device according to this embodiment, the angle of the hook 101 can be adjusted by connecting the support column 202 with the insert 201. After adjusting to a suitable angle, the electromagnet 204 is activated to magnetically fix the support column 202, preventing the support column 202 from rotating. The slider 203 is connected to the support structure to facilitate disassembly and assembly of the support. The two rubber rings 205 on the outer walls of the two support columns 202 can create a certain resistance to the support columns 202, which can slow down the easy rotation of the support columns 202 and achieve the purpose of strengthening stability.

[0040] In this specific embodiment, the upright 301 supports the slider 203 and the hook 101, and is used to adjust the slider 203 up and down, and the magnetic joint is used to fix the slider 203.

[0041] The magnetic block 305 is fixedly connected to the slider 203 and embedded in one side of the slider 203. The slider 203 is slidably connected to the upright 301 and located on one side of the upright 301. There are multiple magnetic joints, each of which is fixedly connected to the upright 301 and embedded inside the upright 301. The slider 203 is slidably connected to the upright 301 and can slide on the upright 301 until it reaches the required height. Then, the corresponding magnetic joint is energized, while the remaining magnetic joints are de-energized, which can save energy. After the magnetic joint is energized, the magnetic block 305 fixes the slider 203.

[0042] Secondly, the magnetic suction plate 302 is fixedly connected to the upright rod 301 and embedded inside the upright rod 301. The two ends of the magnetic column 303 are fixedly connected to the magnetic suction plate 302 and located inside the magnetic suction plate 302. The coil 304 is fixedly connected to the magnetic column 303 and sleeved on the outer wall of the magnetic column 303. When magnetically fixed, the coil 304 is energized, so that the magnetic column 303 generates electromagnetic force and transmits it to the magnetic suction plate 302. The magnetic suction plate 302 is used to achieve magnetic fixation of the magnetic block 305 and complete the positioning of the hook 101.

[0043] When using the surgical muscle retraction device of this embodiment, the slider 203 is slidably connected to the upright 301. The slider 203 can slide on the upright 301 until it moves to the required height. Then, the corresponding magnetic joint is selected and energized, while the other magnetic joints are de-energized, which can save energy. After the magnetic joint is energized, the slider 203 is fixed by the magnetic block 305. During magnetic fixation, the coil 304 is energized, so that the magnetic column 303 generates electromagnetic force and transmits it to the magnetic plate 302. The magnetic plate 302 achieves magnetic fixation of the magnetic block 305, thus completing the positioning of the hook 101.
