Description

Technical Field

[0001] The invention belongs to the field of medical devices, and specifically relates to a head and hand fixing bracket and application thereof. Background Art

[0002] Flap transplantation may be used in ear reconstruction surgery, nose defect repair surgery and other head and facial tissue defect repair surgeries. Flap is formed by skin with blood supply and its attached subcutaneous fat. During the flap formation and transfer process, a part must be connected to the main body (donor flap area). This connected part is called the pedicle to maintain blood supply. The other part is separated from the main body on the surface and deep surface. After being transferred to another wound surface (receiver flap area), it is temporarily supplied with nutrition by the pedicle blood supply. After the blood vessels in the wound surface of the recipient flap area grow into the flap and a new blood supply is established, the pedicle is cut off to complete the whole process of flap transfer. Therefore, it is also called pedicle flap, but the pedicle does not need to be cut after the transfer of local flap or island flap. When a distal flap is used for head and facial tissue defect repair surgery, such as the transfer of the inner arm flap, in order to ensure the survival of the flap, the upper arm needs to be kept close to the head and face for a certain period of time. At this time, a fixed bracket is needed to fix the arm to the patient's head, and the patient is required to force his elbows and wrists to be fixed to the head for more than three weeks.

[0003] The existing fixation method mainly fixes the patient's arm to be transplanted with skin to his head through plaster, and then fixes the elbow and wrist to the head.

[0004] In the prior art, patients are forced to maintain the posture for more than three weeks using plaster fixation, which is time-consuming and laborious, has a large fixation range, leaves the shoulder, elbow, and wrist joints almost without mobility, and the plaster is hard and heavy, overloading the patient's head and shoulders, causing great pain to the patient. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a head-hand fixing bracket and application thereof which can keep the patient's hands on the patient's head without using plaster.

[0006] The technical solution of the present invention to solve the above technical problems is as follows: a head and hand fixing bracket, comprising a retractable cap hoop ring, a plurality of fixing straps and a horizontally arranged wrist strap, wherein;

[0007] The retractable cap hoop ring is provided with a plurality of buckles, the fixing belt corresponds to the buckles one by one and one end of the fixing belt is fixedly connected to the buckle;

[0008] One end of the fixing belt away from the buckle is fixedly connected to the bottom surface of the wristband, and both ends of the wristband are provided with magic sticks that can be bonded to each other.

[0009] The beneficial effect of the present invention is that the retractable cap hoop ring is worn on the patient's head, and then the patient's wrist is worn on the wristband and fixed by Velcro. Since the fixing belt is arranged on the retractable cap hoop ring, the patient's hand is fixed on the patient's head by the fixing belt, so as to assist the patient in the flap transfer process. Moreover, when the head and hand fixing bracket of the present invention is fixed, the patient's shoulder, elbow and wrist have a certain degree of mobility, which reduces the patient's pain and improves the comfort.

[0010] Based on the above technical solution, the present invention can also be improved as follows.

[0011] Further, the retractable cap hoop band comprises a band body and a locking column, wherein:

[0012] One end of the ring belt body is provided with a plurality of through holes, one end of the locking column is hinged to an end of the ring belt body away from the through holes, and the other end of the locking column is used to extend into or out of the through holes.

[0013] The beneficial effect of adopting the above further solution is that when the ring belt body is sleeved on the patient's head, the locking column on one end of the ring belt body extends into the corresponding through hole, so that the diameter of the ring belt body can be adjusted to adapt to the patient's head. The ring belt body with adjustable diameter can adapt to more patients, and the method of adjusting the diameter of the ring belt body is simple and efficient.

[0014] Further, the endless belt body also includes a belt loop, wherein;

[0015] The belt loop is arranged on the endless belt body and is at the same end as the through hole, and one end of the endless belt body away from the through hole is used for inserting or extending the belt loop.

[0016] The beneficial effect of adopting the above further solution is that after the locking column on the endless belt body is inserted into the through hole, one end of the endless belt body is inserted into the belt loop, thereby maintaining the neatness and stability of the head and hand fixing bracket.

[0017] Furthermore, it also includes a chin strap, and the retractable hat hoop ring is provided with two opposite belt holes, and the two ends of the chin strap are respectively sleeved on the two belt holes.

[0018] The beneficial effect of adopting the above further solution is that the chin strap is sleeved on the patient's chin, which prevents the retractable headband ring from falling off, allowing the patient to move in a larger arc without worrying about the head and hand fixing device falling off.

[0019] Furthermore, it also includes an adjustment buckle, and one end of the chin strap passes through the adjustment buckle and the belt hole in sequence and then passes through the adjustment buckle again and is fixedly connected to the adjustment buckle.

[0020] The beneficial effect of adopting the above further solution is that, by extending and retracting the chin strap in the adjustment buckle, the length of the chin strap can be well adjusted, thereby adapting to the chin sizes of more patients.

[0021] Furthermore, the retractable cap hoop band adopts a hoop band assembly, and the hoop band assembly includes a hoop band, a tie, a support cover, a first clamp, a second clamp, an elastic member, a cover plate and a knob, wherein;

[0022] One end of the hoop is connected to the cap shell, and a fixing column perpendicular to the hoop is provided in the middle thereof;

[0023] The lace is provided with an opening extending along the length direction thereof, and one end thereof is inserted into the hoop, and the other end is connected to the cap shell; the lace is passed through the opening and is arranged on the fixing column and corresponds to the hoop, and the two sides of the opening are provided with latch teeth extending along the length direction of the lace;

[0024] The support cover is arranged on the hoop and covers the fixing column;

[0025] A clamping portion for being sleeved on a fixing column and meshing with the clamping teeth of the strap is fixed on one side of the first clamping member, and a first circumferential tooth is fixed on the other side;

[0026] The second clamping member has a second circumferential tooth meshing with the first circumferential tooth;

[0027] The elastic member is arranged on the second clamping member;

[0028] The cover plate is closed on the supporting cover;

[0029] The knob is arranged on the cover plate and is fixedly connected to the second clamping member.

[0030] The beneficial effect of adopting the above further solution is that the present invention also provides a method for adjusting the diameter of the retractable cap hoop ring band, using the first clamp to engage with the lace and the second clamp respectively, when the second clamp is rotated, the lace can move relative to the hoop, thereby tightening the hoop; on the other hand, the second clamp is separated from the first clamp by the cooperation of the knob and the elastic member, so as to realize the quick detachment of the head and hand fixing bracket.

[0031] The present invention also provides an application of the head-hand fixation bracket as described above in treating diseases, wherein the diseases include ear reconstruction surgery, nose defect surgery and other head and facial tissue defect repair surgeries, and the head-hand fixation bracket is used to fix the patient's hands on the patient's head.

[0032] The beneficial effect of the present invention is that when the head and hand fixation bracket of the present invention is used to treat head and facial tissue defects such as external ear defects and nose defects, and when an upper arm medial skin flap transfer operation is required during the plastic surgery, the head and hand fixation bracket can be used to keep the patient's head and hands fixed, and the patient's normal upper arm skin flap can be transferred to the head and facial defect area, thereby achieving the purpose of treatment and recovery.

DETAILED DESCRIPTION

[0042] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0043] Embodiment 1,

[0044] like Figure 1 and Figure 2As shown, a head and hand fixing bracket comprises a retractable cap hoop band 1, a plurality of fixing bands 5 and a horizontally arranged wristband 4, wherein the retractable cap hoop band 1 is provided with a plurality of buckles 101, the fixing bands 5 correspond to the buckles 101 one by one and one end of the fixing band 5 is fixedly connected to the buckle 101. The ends of the fixing bands 5 away from the buckles 101 are fixedly connected to the bottom surface of the wristband 4, and both ends of the wristband 4 are provided with magic adhesive 401 that can be bonded to each other.

[0045] For better effect, optional, such as Figure 3 As shown, it also includes a chin strap 2, and the retractable hat hoop ring belt 1 is provided with two opposite belt holes 102, and the two ends of the chin strap 2 are respectively sleeved on the two belt holes 102. The wearer can better wear the head and hand fixing bracket through the chin strap 2.

[0046] It should be noted that the diameter of the telescopic cap hoop ring 1 is adjustable in various ways, which are described below in two ways: one way and two ways.

[0047] Method 1:

[0048] like Figure 4 and Figure 5 As shown, the retractable cap hoop band 1 includes a band body 103 and a locking column 104, wherein a plurality of through holes 1032 are provided on one end of the band body 103, one end of the locking column 104 is hinged to an end of the band body 103 away from the through hole 1032, and the other end of the locking column 104 is used to extend into or out of the through hole 1032.

[0049] Optional, such as Figure 4 As shown, the endless belt body 103 further includes a belt ring 1031, wherein;

[0050] The belt loop 1031 is disposed on the endless belt body 103 and is at the same end as the through hole 1032 . An end of the endless belt body 103 away from the through hole 1032 is used for inserting into or extending out of the belt loop 1031 .

[0051] For the first method, when treating head and facial tissue defect surgeries such as ear reconstruction surgery and nose defect surgery, the specific operation steps are: after the flap transplantation, the ring belt body 103 is sleeved on the patient's head, and then the locking column 104 is inserted into the corresponding through hole 1032, and then one end of the ring belt body 103 is inserted into the belt loop 1031, so that the ring belt body 103 is fixedly sleeved on the patient's head. Then the patient's wrist is put on the wristband 4 and fixed by the magic stick 401. Since the fixing belt 5 is arranged on the retractable hat hoop ring belt 1, the patient's hand is fixed on the patient's head by the fixing belt 5, which assists the patient in the flap transfer process.

[0052] Method 2:

[0053] As shown in Figure 6 and Figure 7 The retractable cap hoop band 1 adopts a hoop assembly 3, which includes a hoop 31, a tie 32, a support cover 33, a first clamp 34, a second clamp 35, an elastic member 36, a cover plate 37 and a knob 38, wherein one end of the hoop 31 is connected to the cap shell 1, and a fixing column 311 perpendicular to the hoop 31 is provided in the middle thereof. The tie 32 is provided with an opening 321 extending along its length direction, and one end thereof is inserted into the hoop 31, and the other end is connected to the cap shell 1; the tie 32 is passed through the opening 321 and is provided on the fixing column 311 and corresponds to the hoop 31, and the two sides of the opening 321 are provided with latch teeth 322 extending along the length direction of the tie 32. The support cover 33 is provided on the hoop 31 and covers the fixing column 311. The first clamping member 34 has a clamping portion 342 fixed on one side thereof for being sleeved on the fixing column 311 and meshing with the clamping teeth 322 of the lace 32, and a first circumferential tooth 341 fixed on the other side thereof. The second clamping member 35 has a second circumferential tooth 351 meshing with the first circumferential tooth 541, and the elastic member 36 is disposed on the second clamping member 35. The cover plate 37 is covered on the support cover 33. The knob 38 is disposed on the cover plate 37 and is fixedly connected to the second clamping member 35.

[0054] In the specific operation process of adjusting the telescopic cap hoop band 1, the support cover 33 is arranged on the band 31 and covers the fixed column 311, and is used to support other components of the adjustment band assembly 3; a hole is provided on each of its two corresponding circumferential surfaces, and is used to pass a lace 32. The first clamp 34 is a hard sheet-like cylinder, which is connected to the fixed column 311 through a screw rod. In addition to its circumferential surface, it also has two side surfaces, one side surface is close to the lace 32 (named as the inner side surface), and the other side surface is away from the lace 32 (named as the outer side surface). Its inner side surface is fixed with a clamping part 342 for being set on the fixed column 311 and meshing with the clamping teeth 322 of the lace 32. When the first clamp 34 rotates, the synchronous rotation of the clamping part 342 can drive the clamping teeth 322, and then drive the movement of the lace 32, so as to realize the relative movement of the lace 32 and the band 31; its outer side surface is fixed with a first circumferential tooth 341 forming a circular ring. The second clamp 35 is meshed with the first circumferential teeth 341 through the second circumferential teeth 351 on its side, so that when the second clamp 35 rotates, it can drive the first circumferential teeth 341 through the second circumferential teeth 351, and then drive the first clamp 34 to rotate synchronously; its other side (i.e., the end away from the first clamp 34) is provided with a convex portion, and the center of the convex portion is provided with a non-circular second fixing hole. The elastic member 36 is a spring, which is directly sleeved on the convex portion of the second clamp 35; and the cover plate 37 is covered on the support cover 33 and contacts with the elastic member 36. When the elastic member 36 is in a normal state, the second clamp 35 is meshed with the first clamp 34 under the action of the elastic member 36 (engaged with the first circumferential teeth 341 through the second circumferential teeth 351); and when the second clamp 35 moves upward due to the external force, the elastic member 36 is compressed by force, and the second clamp 35 and the first clamp 34 are separated. The knob 38 is disposed on the cover plate 37 and is fixedly connected to the second clamp 35 through a screw. This is because the knob 38 is provided with a clamping column that matches the second fixing hole. When the clamping column is inserted into the second fixing hole, rotating the knob 38 can drive the second clamp 35 to rotate, thereby driving the first clamp 34 to rotate, and finally realizing the relative movement of the lace 32 and the hoop 31. When the diameter of the hoop 31 needs to be increased, the knob 38 can be pulled outward, which can drive the second clamp 35 connected thereto to move outward, and then compress the elastic member 36 to separate the second clamp 35 from the first clamp 34; since the lace 32 is also subjected to an outward pulling force, the lace 32 can move outward relative to the hoop 31 to increase the diameter of the hoop 31, and vice versa, the diameter of the hoop 31 is reduced.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
