Description

Technical Field

[0001] This utility model relates to the field of medical fixation devices, specifically to a finger fixation device for hand and foot surgery. Background Technology

[0002] In hand and foot surgery, immobilization after finger fractures is of great significance, mainly in the following aspects: 1. Promoting fracture healing. 2. Reducing pain. 3. Preventing further injury. 4. Facilitating care and rehabilitation. Currently, traditional finger immobilization devices are broadly classified into two types. One type uses 3D printing or customization to create a hand-like immobilizer based on the patient's hand shape, which the patient wears to directly fix the finger. The other type is a finger sleeve, which is worn on the affected finger, with an arm sleeve extending to the forearm from the base of the finger sleeve, locking it to the patient's forearm. However, both of these methods either have long production cycles and high costs, or fail to effectively adapt to the patient's hand, resulting in less than ideal immobilization effects. Summary of the Invention

[0003] The purpose of this invention is to provide a hand and foot surgical finger fixation device that offers a flexible fixation method and can adapt to the needs of patients with different finger circumferences.

[0004] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows: a hand and foot surgical finger fixation device, comprising several fixing rings and connecting rods for connecting the fixing rings; an inflatable air bladder is provided on the inner surface of the fixing ring; an annular groove is provided on the outer wall of the middle section of the fixing ring, and a rotating ring is fitted inside the annular groove of the fixing ring, and at least two plugs for the ends of the connecting rods to be inserted into the rotating ring.

[0005] Preferably, the air inlet of the inflatable airbag is located on the outer side of one end of the fixed ring, and a valve core is provided at the air inlet.

[0006] Preferably, the rotating ring has two connectors, and the two connectors are located on the same straight line extending along the length direction of the rotating ring.

[0007] Preferably, the connector is tubular, and the size of the inner cavity of the connector matches the size of the end of the connecting rod; a locking disc is provided near the end of the connecting rod, and a locking cap that forms a threaded engagement with the connector is also sleeved on the locking disc, so that the locking disc on the connecting rod can be pressed tightly onto the connector by the locking cap.

[0008] The beneficial effects of this invention are mainly reflected in its highly flexible fixation method, which can adapt to patients with various finger circumferences. Specifically, during use, the fixation rings are first placed on the patient's finger joints as needed. Utilizing the expansion of the inflatable bladder, this invention can adapt to patients with various finger circumferences and can be adjusted according to the patient's recovery period (e.g., the finger circumference is larger in the early stages of swelling and smaller after the swelling subsides). Generally, no fewer than three fixation rings should be worn: two fixed to the two ends of the injured joint of the injured finger, and the third fixed to the healthy finger. The fixation rings are then connected in a triangular shape using a connecting rod. This invention provides reliable fixation, is compact in size, and can adapt to different fixation needs. Attached Figure Description

[0011] Figure 3 This is a schematic diagram of the connecting rod. Detailed Implementation

[0012] like Figure 1-3 The invention illustrates a hand and foot surgical finger fixation device, primarily used for immobilizing fingers in cases of finger deformities, finger sprains, etc. In general, this invention includes several fixing rings 1 and connecting rods 2 for connecting the fixing rings 1. Typically, there are at least three fixing rings 1, and at least two. With two rings, each ring can be worn on a different phalanx of the finger joint, and the connecting rods 2 connect them to prevent movement of the corresponding phalanx. With three fixing rings 1, the third fixing ring 1 can be installed on the healthy finger, thus achieving positioning and fixation of the affected finger. Of course, it can also be used for fixing multiple fingers to correct deformities, but these applications will not be listed here.

[0013] like Figure 2As shown, the inner surface of the fixing ring 1 of this invention is provided with an inflatable air bladder 3. To facilitate the inflation and deflation of the inflatable air bladder 3, the air inlet 7 of the inflatable air bladder 3 is generally located on the outer side of one end of the fixing ring 1. An air valve core is provided at the air inlet 7, allowing for inflation via a syringe or air gun. A particularly noteworthy feature of this invention is that an annular groove 4 is provided on the outer wall of the middle section of the fixing ring 1. A rotating ring 5 is fitted inside the annular groove 4 of the fixing ring 1. The rotating ring 5 is provided with at least two connectors 6 for inserting the ends of the connecting rods 2. By placing the connectors 6 on the rotating ring 5, the circumferential position of the connectors 6 can be adjusted using the rotating ring 5, thereby improving ease of use. For example, the position of the connecting rod 2 can be adjusted to the back of the hand or the palm. The rotating ring 5 has two connectors 6, and the two connectors 6 are located on the same straight line extending along the length of the rotating ring 5. That is, one fixing ring 1 can be connected to at least two fixing rings 1 via the connecting rod 2.

[0014] In use, the connecting rod 2 can be bent as needed to adjust its shape, thereby more comprehensively adapting to the fixation needs of the fingers. However, both ends of the connecting rod 2 should be able to be stably connected to the connector 6.

[0015] In use, this invention involves first placing the fixing rings on the patient's finger joints as needed. The expansion of the inflatable air bladder 3 allows it to accommodate patients with various finger sizes and can be adjusted according to the patient's recovery period (e.g., larger finger circumference in the early stages of swelling, smaller circumference after swelling subsides). Generally, no fewer than three fixing rings 1 should be worn: two fixed to the ends of the injured finger joint, and the third fixed to the healthy finger. The connecting rod 2 then connects the fixing rings 1 into a triangular shape. This invention provides secure fixation, is compact, and can adapt to different fixation needs.

[0016] In addition, to further improve the stability of the connection between the connecting rod 2 and the connector 6, the connector 6 is tubular, and the size of the inner cavity of the connector 6 matches the size of the end of the connecting rod 2. A locking disc 8 is provided near the end of the connecting rod 2, and a locking cap 9 that forms a threaded engagement with the connector 6 is also fitted over the locking disc 8. The locking disc 8 on the connecting rod 2 can be pressed tightly onto the connector 6 by the locking cap 9.
