Description

Technical Field

[0001] The utility model relates to the technical field of skull traction devices, in particular to a skull traction device with adjustable height. Background Art

[0002] It is well known that patients with vertebral fracture and spinal cord injury usually suffer from quadriplegia, urinary retention, intercostal muscle paralysis, and respiratory weakness after the injury, especially those with high cervical spinal cord injury, which makes breathing more difficult. In addition, due to the instability of the cervical spine, the cervical spinal cord injury may be aggravated, making the injury more serious. In order to quickly stabilize the condition, skull traction should be performed as soon as possible. Skull traction can reduce or eliminate the compression of the spinal cord and prevent the movement of fractured vertebrae and aggravate the spinal cord injury. The commonly used skull traction method is to fix the skull traction arch on the patient's skull to perform traction. Skull traction is mainly used to treat patients with trauma such as cervical fracture and dislocation, cervical compression fracture or depressed skull fracture.

[0003] During use of the existing skull traction device, when the weight is adjusted, the weight will cause the traction rope to shake, and the weight exposed to the outside may be bumped and shaken by people, affecting the treatment of the patient. The traction rope cannot be fixed and loosened for adjustment, and the traction rope can only be fixed by people manually holding it, which is inconvenient for people to assemble or disassemble the traction frame. Moreover, the height position of the counterweight mechanism cannot be adjusted, and people need to squat to adjust the weight of the counterweight mechanism, which is extremely inconvenient to use. Therefore, it is necessary to propose a solution to this technical problem. Utility Model Content

An elastic component 10 is provided between the adjusting slot and one end of the supporting box 3, a connecting hole is provided between the adjusting slot and one end of the supporting box 3, a connecting column 11 is provided on the connecting hole, a limiting mechanism is provided between the connecting column 11 and the connecting hole, and a locking mechanism is provided between one side of the supporting box 3 and the adjusting plate 8. In this embodiment, a person assembles the adjusting plate 8 on the patient's head by using a traction frame 6. The traction frame 6 is a common medical head traction frame 6 in the prior art and is not described in detail in this structure. Then, the weight of the counterweight mechanism is adjusted according to the traction force requirement, and then the locking mechanism is closed. The locking mechanism is used to fix and lock the adjusting plate 8 inside the adjusting slot, and the locking body is stopped by closing the locking frame. The locking adjustment plate 8 can drive the adjustment plate 8 to move by pushing the connecting column 11, and the adjustment plate 8 drives the tooth block 9 to move. The tooth block 9 leaves the tooth plate 7, and the elastic component 10 is squeezed and contracted by the adjustment plate 8. The counterweight mechanism moves the tooth plate 7 downward in the slot through the influence of gravity, so that the traction rope 5 pulls the traction frame 6 through the pulley 4, so that the traction frame 6 pulls the head, which is convenient for the treatment of patients with trauma such as cervical fracture dislocation, cervical compression fracture or depressed skull fracture. When treatment is not needed, the personnel loosens the connecting column 11, so that the elastic component 10 supports the adjustment plate 8, so that the tooth block 9 is against the tooth plate 7, and the tooth plate 7 is fixed in the slot, which is convenient for the personnel When the traction frame 6 is removed from the skull, the limiting mechanism can prevent the connecting column 11 from leaving the connecting hole. By pushing the connecting column 11, the tooth block 9 is separated from the tooth plate 7. Then the person adjusts the height of the counterweight mechanism by lifting or pushing the tooth plate 7 downward. After reaching the height specified by the person, the connecting column 11 is released to enable the tooth block 9 to fix the tooth plate 7, thereby facilitating the person to adjust the weight of the counterweight mechanism and reducing the need for the person to squat or bend excessively. The structure is easy to use and can quickly and conveniently open or close the traction operation on the skull, eliminating the traditional situation in which the person needs to carry the counterweight mechanism to close the traction mechanism, thereby saving the person's physical strength and improving operating efficiency.

[0025] In this embodiment, the limiting mechanism includes a limiting groove and a limiting block 12. The limiting groove is opened between the connecting hole and the adjusting groove. The limiting block 12 is located in the limiting groove. The limiting block 12 is connected to the connecting column 11. The connecting column 11 in the connecting hole is connected by the limiting block 12 in the limiting groove, so that the connecting column 11 can be limited to prevent the connecting column 11 from leaving the connecting hole.

[0026] In the present embodiment, the locking mechanism includes a controller 13 and a fixing groove, wherein the fixing groove is opened at one end of the adjusting groove, and the controller 13 is installed on one side of the supporting box 3. An electromagnetic lock 14 is provided on the fixing groove, and an iron plate 15 is provided between the fixing groove and the adjusting plate 8. The electromagnetic lock 14 can be opened by the controller 13, so that when the tooth plate 7 needs to be fixed, the electromagnetic lock 14 can adsorb the iron plate 15 between the adjusting plate 8 and the fixing groove, thereby fixing the adjusting plate 8 and the tooth block 9, so that the tooth plate 7 against which the tooth block 9 is pressed is fixed in the slot, which can improve the fixing reliability of the tooth plate 7 and prevent people from accidentally touching the connecting column 11, causing the tooth plate 7 to become loose in the slot. Closing the electromagnetic lock 14 by the controller 13 can facilitate the use of the connecting column 11.

[0027] In this solution, the counterweight mechanism includes a counterweight box 16 and a counterweight block 17. The counterweight box 16 is installed at the bottom end of the tooth plate 7. A threaded groove is provided at the bottom end of the counterweight box 16. The counterweight block 17 is threadedly connected to the threaded groove. By rotating the counterweight block 17, the counterweight block 17 can be easily assembled or removed from the threaded groove, making it convenient for personnel to adjust the weight of the counterweight box 16 according to the required traction force range.

[0028] In this solution, a plurality of counterweight blocks 17 are provided. By providing a plurality of counterweight blocks 17, the traction force can be improved to meet the demand for greater traction force.

[0029] In this solution, a handle is provided on the connecting column 11, and the handle on the connecting column 11 can facilitate a person to hold the connecting column 11 for use.

[0030] In this solution, a plurality of elastic components 10 are provided, and the adjustment plate 8 can be supported more stably by the plurality of elastic components 10 , so that the tooth block 9 can be more firmly pressed against the tooth plate 7 .

[0031] In this solution, the elastic component 10 is a spring, which has the characteristic of good elasticity, thereby being able to improve the supporting effect on the adjustment plate 8.
