Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to a surgical limb expander. Background Art

[0002] Currently, joint surgery is plagued by a limited operating table height, making it difficult to adjust the height of the patient's limb during surgery. While the operating table has built-in limb adjustment capabilities, adjusting the limb's position and height once the procedure has begun is challenging. Utility Model Content

[0003] In order to solve the problems in the background technology, the utility model provides a surgical limb expander.

[0004] The specific technical solutions of the utility model are as follows:

[0005] A surgical limb extender includes a horizontal bar and a vertical bar, wherein the upper end of the vertical bar is connected to the middle portion of the horizontal bar. A plurality of pulleys are disposed on the horizontal bar below the horizontal bar. The horizontal bar is tilted, with the highest point of the horizontal bar being the distal end and the lowest point being the proximal end. A hand-cranked wire reel wheel is disposed at the proximal end of the horizontal bar, and a locking device for the hand-cranked wire reel wheel is provided. The device also includes a steel wire rope, one end of which is fixed to the hand-cranked wire reel wheel, and the other end of which passes through each pulley in sequence and is hung below the distal end of the horizontal bar and is provided with a buckle.

[0006] Furthermore, the acute angle between the horizontal bar and the vertical bar is 75 degrees.

[0007] Furthermore, a crossbar fixing structure is provided at the upper end of the vertical bar, which can adjust and fix the position of the crossbar relative to the vertical bar.

[0008] Furthermore, the crossbar fixing structure includes a first sliding groove and a first tightening screw arranged on the first sliding groove. The crossbar can be slidably arranged in the first sliding groove, and after the position is adjusted, it is fixed by the first tightening screw.

[0009] Furthermore, a bedside fixture is provided on the vertical rod, and the bedside fixture can adjust and fix its position relative to the vertical rod.

[0010] Furthermore, the bedside fixer includes a second sliding groove, a hanging fixing structure and a second tightening screw arranged on the second sliding groove. The hanging fixing structure is hung and fixed on the side of the operating bed, and the vertical rod is slidably arranged in the second sliding groove. After the position is adjusted, it is fixed by the second tightening screw.

[0011] Furthermore, the suspension fixing structure is in an inverted U shape.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] This new device allows for convenient adjustment of the height of a patient's limbs during surgery, resolving the issue of limited operating table height adjustment, which prevents the patient's limbs from being adjusted during surgery. Both the height of the vertical bar and the position of the horizontal bar can be adjusted freely, enhancing practicality. The tilted horizontal bar makes it easier for medical staff to operate the hand-cranked reel. BRIEF DESCRIPTION OF THE DRAWINGS

They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as a limitation on the utility model.

[0017] The terms “first”, “second”, etc. are only used for distinguishing descriptions and should not be understood as indicating or implying relative importance.

[0018] In the description of this embodiment, it should also be noted that, unless otherwise clearly specified and limited, the terms "set", "connected" and "connect" should be understood in a broad sense.

[0019] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0020] See also Figure 1This embodiment discloses a surgical limb expander, comprising a horizontal bar 100 and a vertical bar 200, wherein the upper end of the vertical bar 200 is connected to the middle of the horizontal bar 100, and the acute angle between the horizontal bar 100 and the vertical bar 200 is preferably 75 degrees. A plurality of pulleys 110 are provided on the lower side of the horizontal bar 100. The high point of the horizontal bar 100 is the distal end, and the low point is the proximal end. A hand-cranked wire drum wheel 120 is provided at the proximal end of the horizontal bar 100, and a locking device 130 for the hand-cranked wire drum wheel 120 is provided, which can lock the hand-cranked wire drum wheel 120 at any time. It also includes a steel wire rope 140, one end of which is fixed to the hand-cranked wire drum wheel 120, and the other end passes through each pulley 110 in turn, and is hung below the distal end of the horizontal bar 100, and is provided with a buckle 141 for fixing the limbs. By rotating the retractable hand-cranked reel wheel 120, the retractable length of the wire rope 140 is controlled.

[0021] The principles and usage of this embodiment are as follows:

[0022] Before surgery, the vertical rod 200 of the limb expander of this embodiment is secured to the operating table or the ground. The patient lies on the operating table, and the limbs of the joints requiring surgery are secured with buckles 141. During surgery, if the limb's height needs to be adjusted, the locking device 130 is opened, and the hand-cranked wire reel wheel 120 is rotated to retract and release the wire rope 140, thereby adjusting the height of the limb secured by buckle 141. Once the limb's height meets the desired level, the locking device 130 is then used to lock the hand-cranked wire reel wheel 120.

[0023] As a further solution of this embodiment, a crossbar fixing structure 210 is provided at the upper end of the vertical rod 200 to adjust and fix the position of the crossbar 100 relative to the vertical rod 200. Preferably, the crossbar fixing structure 210 includes a first sliding groove 211 and a first tightening screw 212 disposed on the first sliding groove 211. The crossbar 100 can be slidably disposed in the first sliding groove 211 and, after the position is adjusted, is fixed by the first tightening screw 212.

[0024] As a further solution to this embodiment, a bedside fixture 220 is provided on the vertical rod 200. The bedside fixture 220 can be adjusted relative to the vertical rod 200 and fixed. Preferably, the bedside fixture 220 includes a second sliding slot 221, a hanging fixing structure 222, and a second tightening screw 223 disposed on the second sliding slot 221. The hanging fixing structure 222 is suspended and fixed to the side of the operating bed. The vertical rod 200 slides within the second sliding slot 221 and, after adjusting its position, is secured with the second tightening screw 223. This technical solution allows the height of the vertical rod 200 to be adjusted at will. Preferably, the hanging fixing structure 222 is in an inverted U-shape.

[0025] The above only describes in detail the preferred embodiments of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
