Description

Technical Field

[0001] This utility model relates to the field of medical device auxiliary equipment technology, and in particular to a medical energy cable storage device that can automatically rewind. Background Technology

[0002] In modern surgery, surgeons often use various energy-powered instruments such as electrocautery, bipolar electrocoagulation, ultrasonic scalpels, laparoscopy, or robots. These devices are connected to the main unit via long power cables. While long cables offer operational flexibility, they also create numerous problems during surgery, including messy stacking, tangling, risk of contamination, and limited operating space. Currently, there is no simple and easy-to-use power cable management device that meets the dual requirements of sterile storage and efficient operation in clinical practice. For example, patent CN111542366A discloses a medical auxiliary device, including a support body; a winding part that is rotatable relative to the support body around a support axis and winds the medical device; and a connecting part located in the winding part and connected to the end of the medical device. However, the cable in this auxiliary device cannot be automatically wound, and its ease of use is still lacking.

[0003] Therefore, it is of great significance to design a cable storage device that can be pre-wound before surgery, used stably during surgery, and automatically recycled after surgery. Utility Model Content

[0004] The purpose of this invention is to provide an automatic rewinding medical energy cable storage device. This device can realize pre-winding of cables before surgery, stable use during surgery, and automatic rewinding of cables after surgery, making it flexible and convenient to use.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] An automatically retractable medical energy cable storage device includes a central shaft, a first cable box and a second cable box respectively disposed at both ends of the central shaft, and a cable. Each cable box includes a cover plate and a cover. The cover plate is sleeved on the central shaft, and the cover is rotatably connected to and detachable from the central shaft. A spring is provided in the inner cavity of the central shaft. One end of the spring is connected to the center of the inner top surface of the cover of the first cable box, and the other end is connected to the inner wall of the central shaft. The first cable box and the second cable box are provided with openings for the cable to pass through.

[0007] In this invention, the first and second cable boxes are set independently at both ends of the central shaft, thereby ensuring that the instrument end connection and the host end connection of the cable do not interfere with each other, and achieving stable use during surgery.

[0008] Preferably, the inner top surface of the cover of the first and second junction boxes is provided with a plurality of elastic buckle blocks evenly distributed around the periphery, and each elastic buckle block is provided with buckle arms protruding inward on both sides of the bottom, and the outer wall of the central shaft is provided with an annular groove that matches the buckle arms.

[0009] In this invention, the first and second cable boxes are rotatably connected to the central shaft through the cooperation of the elastic buckle block on the box cover and the annular groove of the central shaft. They are also detachable, which makes it convenient for medical staff to clean, maintain and reuse them, and facilitates the pre-winding of cables before surgery.

[0010] Preferably, a first spring mounting block is provided at the center of the inner top surface of the first junction box cover. The first spring mounting block has a first snap-fit ​​groove, and one end of the spring is bent to form a first snap-fit ​​connector and snaps into the first snap-fit ​​groove.

[0011] More preferably, the opening direction of the first snap-fit ​​groove is parallel to the axis of the central shaft.

[0012] Preferably, a second spring mounting block is provided on the inner wall of the central shaft, the second spring mounting block has a second snap-fit ​​groove, and the other end of the spring is bent to form a second snap-fit ​​joint and snap-fitted into the second snap-fit ​​groove.

[0013] More preferably, the opening direction of the second snap-fit ​​groove is parallel to the axis of the central shaft.

[0014] In this invention, a spring is installed between the first wire box and the central shaft. As the central shaft rotates relative to the first wire box, energy is stored in the spring, which then enables automatic rewinding. Compared to traditional external rewind boxes or electric winding systems, this structure is more compact, safer, and more portable, making it suitable for use in sterile operating tables.

[0015] In this invention, the first spring mounting block and the second spring mounting block enable the detachable installation of the spring.

[0016] Preferably, the top surface of the cover and the cover plate of the first junction box are respectively provided with a first cover opening and a first cover plate opening that are corresponding in the axial direction; the cover plate and the bottom surface of the second junction box are respectively provided with a second cover plate opening and a second cover opening that are corresponding in the axial direction.

[0017] Preferably, the cable passes through the first cover opening, the first cover plate opening, the second cover plate opening, and the second cover opening in sequence.

[0018] Preferably, the cable end passing through the opening of the first cover is the instrument end connection end, and the cable end passing through the opening of the second cover is the host end connection end. The cable portion located inside the first cable box and the cable portion located inside the second cable box are wound around the outer surface of the central shaft.

[0019] Preferably, cable limiting components are provided outside the openings of the first and second lids.

[0020] Preferably, the cable limiting assembly includes a clamp body, the clamp body includes a pair of clamp arms that are hinged to each other, the handle portion of the clamp arms is provided with a spring, and the jaw portion of the clamp arms is used to clamp the cable.

[0021] More preferably, the jaws are fitted with a soft pad to protect the cable.

[0022] The cable limiting component in this invention allows medical staff to easily achieve a smooth "temporary limiting-release-re-clamping" action during operation. This structure is particularly suitable for rapid operation in the surgical environment, combining locking stability with ease of use.

[0023] Preferably, the opening is provided with an anti-wear protective sleeve.

[0024] Preferably, the covers of the first junction box and the second junction box are provided with mounting structures, the mounting structures including buckles.

[0025] Preferably, the lids of the first and second suture boxes are provided with anti-slip textures to ensure that the operator wearing gloves can stably hold and operate the device during surgery, thereby enhancing the human-machine ergonomic experience.

[0026] In this invention, the covers of the first and second suture boxes are rotatable relative to the central shaft. The first suture box contains the instrument end of the cable, while the second suture box contains the main unit end. In use, the cover is held or fixed, and the cable is pulled directly. The cable wound around the central shaft rotates the central shaft. A spring between the first suture box and the central shaft stores energy. After surgery, this energy allows the instrument end of the cable to automatically rewind back into the first suture box. The main unit end connection requires less flexibility than the instrument end connection and the cable can be manually retrieved.

[0027] In this invention, when pre-wrapping, pulling out, or retrieving the cable, neither end of the cable needs to be connected to surgical instruments or a power unit.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] (1) This utility model, through the setting of a central shaft, a first wire box that is rotatable and detachable relative to the central shaft, a second wire box, and a spring, can realize the pre-winding of the cable before surgery, stable use during surgery, and automatic winding of the cable after surgery, making it flexible and convenient to use.

[0030] (2) In this utility model, an annular groove is provided on the outer wall of the central shaft, and an elastic buckle block is provided on the cover of the cable box. The elastic buckle block is provided with a buckle wall. When installing, the cover is pressed down, the elastic buckle block is pushed outward, and the buckle arm is inserted into the annular groove. When disassembling, the cover is pulled up, the elastic buckle block is pushed outward, and the buckle arm is dislodged from the annular groove. This utility model realizes the pre-winding of the cable before surgery and the cleaning after surgery through the above-mentioned structural settings.

[0031] (3) In this utility model, the first wire box, the second wire box cover and the central shaft can be rotated and connected by the cooperation of the central shaft annular groove and the buckle arm, and are not easy to fall off. When using, you can hold or fix the cover and pull the cable. In addition, this utility model is also equipped with a cable limiting component for cable fixing, so as to achieve stable use during operation.

[0032] (4) In this utility model, a spring is embedded in the inner cavity of the central shaft. The spring connects the first wire box cover and the central shaft. When the cable at the end of the instrument is pulled out, the central shaft rotates relative to the first wire box cover, which causes the spring to be stretched and stores the spring potential energy. When the cable is wound up, the spring releases energy and resets, which causes the central shaft to rotate in the opposite direction and reset, thereby realizing the automatic winding of the cable.

[0033] (5) The present invention can complete the pre-winding and sterilization of the power cable before the operation, which improves the preparation efficiency; the cable instrument end can be locked during the operation, which is safe and flexible to use; the automatic recycling function makes the postoperative cleaning quick and clean, saving nurses' operation time; it can be repeatedly sterilized and used, reducing the expenditure of disposable consumables, which is in line with the trend of environmental protection; it reduces the scattered stacking of cables, and improves the operation space and aseptic safety during the operation.

The first junction box 2 and the second junction box 3 are respectively located at both ends of the central shaft 1. Each junction box consists of a cover plate 5 and a box cover 6. The cover plate 5 is sleeved on the central shaft 1, and the box cover 6 is detachably rotatably connected to the central shaft 1. A spring 7 is embedded inside the central shaft 1. One end of the spring 7 is connected to the center of the top of the box cover of the first junction box, and the other end is connected to the inner wall of the central shaft 1. Both the first junction box 2 and the second junction box 3 are provided with openings for the cable 4 to pass through.

[0046] Example 2

[0047] A medical energy cable storage device with automatic retraction includes a central shaft 1, a first cable box 2 and a second cable box 3, with the first cable box 2 and the second cable box 3 respectively disposed at both ends of the central shaft 1, and a cable 4 passing through the two cable boxes.

[0048] In this embodiment, as Figure 4 , 5 As shown, several elastic buckle blocks 8 are evenly distributed around the top surface of the cover 6 of the first junction box 2 and the second junction box 3. Each elastic buckle block 8 has a buckle arm protruding inward on both sides of its bottom end. A corresponding annular groove 9 is provided on the outer wall of the central shaft 1. The buckle arm can be inserted into the annular groove 9 to realize the rotatable connection and detachment of the junction box and the central shaft 1.

[0049] In this embodiment, the top surface of the cover 6 of the first junction box 2 and the cover plate 5 are respectively provided with a first cover opening 12 and a first cover plate opening 13, which are axially aligned; the bottom surface of the cover plate 5 of the second junction box 3 and the cover 6 are respectively provided with a second cover plate opening 14 and a second cover opening 15, which are also axially aligned.
