Description

Technical Field

[0001] This utility model relates to the field of surgical aids technology, and in particular to a tie-on surgical drape. Background Technology

[0002] Hybrid surgery combines craniotomy with endovascular techniques, providing a one-stop, precise diagnosis and treatment for cerebrovascular diseases. It is primarily used in the treatment of complex cerebrovascular conditions, effectively improving patient prognosis.

[0003] During complex surgeries, medical staff will prepare a surgical drape for the patient's head, which includes a film with pre-drilled holes for the specific surgical site. The surgeon will then perform the procedure through these pre-drilled holes. The drape primarily serves to cover the surgical site, preventing contamination by bacteria and other substances, thereby reducing the risk of postoperative infection.

[0004] The currently used surgical drape (film type) has the following problems when placed on a specific part of the patient's body (head):

[0005] Its drooping part can interfere with the rotation scanning process of the C-arm CT scanner, and may easily cause the scanner to become entangled with the surgical drape. In this case, the surgical drape may be pulled away from the patient due to strong force, which may lead to medical accidents and endanger the patient's life.

[0006] Therefore, this utility model provides a tie-on surgical drape. Utility Model Content

[0007] The purpose of this invention is to address the shortcomings of existing technologies and provide a tie-on surgical drape.

[0008] To achieve the above objectives, this utility model adopts the following technical solution: a tie-on surgical drape, comprising:

[0009] Surgical drapes are used to cover the patient's body.

[0010] An opening, which is placed on a surgical drape, is used for surgical procedures and observation;

[0011] Ties, which are disposed on both sides of the surgical drape, are used to secure the surgical drape to the operating table;

[0012] The fastener is used to securely connect the two ties on both sides of the surgical drape;

[0013] The positioner is movably installed between two straps. The positioner includes a first positioning block and a second positioning block and a third positioning block inserted on both sides of the first positioning block. The first positioning block, the second positioning block and the third positioning block are all provided with symmetrical slots for accommodating the straps. The slots are rotatably connected to fixed rollers arranged symmetrically on both sides for smooth insertion and fixation of the straps.

[0014] In one preferred embodiment, the fastener consists of an upper fastening block and a lower fastening block;

[0015] The upper fixing block has locking springs on both sides of its bottom, and the lower fixing block has locking slots on both sides of its top. The locking springs match the locking slots to achieve a locking connection between the two and provide initial fixing force.

[0016] The straps are fixed to the side of the lower fixing block, thereby ensuring that the surgical towel maintains a stable position and shape during use.

[0017] In a preferred embodiment, a fixing pin is fixed at the bottom center of the upper fixing block and is located to the side of the engaging spring piece. An insert block is provided at the top center of the lower fixing block to receive the fixing pin of the upper fixing block, forming a stable insertion structure and enhancing the fixing effect.

[0018] In one preferred embodiment, the engaging spring has a "J"-shaped structure.

[0019] In a preferred embodiment, the engaging slot is an "L"-shaped opening structure.

[0020] In a preferred embodiment, the bottom end of the strap is provided with a circular band.

[0021] In one preferred embodiment, a plurality of convex balls are fixed on the fixed rollers arranged symmetrically on the upper and lower sides.

[0022] In a preferred embodiment, positioning holes are provided on both sides of the first positioning block, and positioning posts are fixed on the sides of both the second and third positioning blocks, with the positioning posts inserted into the positioning holes.

[0023] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0024] This invention uses fasteners to firmly secure the straps to both sides of the surgical drape, and a locator to fix the two straps, preventing the bottom ends of the straps from drooping off the operating table and affecting the rotation scanning of the C-arm CT scanner. The locator avoids the drooping ends that occur when using slip knots or fixed knots to fix the two straps, and also avoids the increased workload and cost of custom-cutting the surgical drape. Only a roughly sized surgical drape needs to be cut, and the straps, fasteners, and locators can be installed one by one for use. The straps, fasteners, and locators can be sterilized and reused multiple times, greatly saving medical supplies. It also solves the problem that when using film-type surgical drapes to cover specific parts of the patient, the drape can easily become entangled, causing strong pulling that can lead to the drape detaching from the patient, resulting in medical accidents and endangering the patient's life.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] like Figures 1-5 As shown, this embodiment provides a technical solution: a tie-on surgical drape, including a surgical drape 1, an opening 2, a tie 3, a fixing element 4, and a positioning device 5. The surgical drape 1 covers the patient's body to cover the surgical site and prevent bacteria and other substances from contaminating the surgical site. The surgical drape 1 is a disposable cloth product, which, due to the properties of the cloth, can absorb blood, liquid, or secretions flowing from the surgical site, keeping the surgical site clean. The opening 2 is formed in the surgical drape 1 (e.g., Figure 1 As shown), the size and position of the opening can be adjusted according to surgical needs, thereby facilitating surgical operation and observation. The ties 3 are installed on both sides of the surgical drape 1 (as shown). Figure 1 As shown), it is used to fix the surgical towel 1 to the operating table, and the bottom end of the tie 3 is fixed with a round strap 31 (as shown). Figure 2 As shown), the tie 3 and the round strap 31 are an integral structure made of nylon. Nylon has good flexibility and bending resistance, which can ensure portability when fixed and prevent the tie 3 from sagging. The fixing component 4 consists of an upper fixing block 41 and a lower fixing block 42 (as shown). Figure 3 As shown), it is used to securely connect two straps 3. The two straps 3 are installed on the lower fixing block 42 by fixing bolts. The bottom sides of the upper fixing block 41 are fixed with "J"-shaped engaging springs 411. The engaging springs 411 are made of tough iron or plastic. The top sides of the lower fixing block 42 are provided with "L"-shaped openings 421. The two are matched to achieve a snap-fit ​​connection and provide initial fixing force. The bottom center of the upper fixing block 41 is fixed with a fixing pin 412. The top center of the lower fixing block 42 is provided with an insert block 422. The insert block 422 is made of sponge or silicone and is installed by adhesive. The fixing pin 412 is inserted into the insert block 422 to form a stable insertion structure and further enhance the fixing effect. The positioner 5 can be movably installed between the two straps 3 (e.g., Figure 1 As shown), the positioner 5 is used to adjust the position and shape of the surgical drape 1. It includes a first positioning block 51, a second positioning block 52, and a third positioning block 53, each with symmetrically arranged slots (as shown). Figure 4 As shown), it is used to accommodate the strap 3, and the slot is rotatably connected with fixed rollers 56 arranged symmetrically on the upper and lower sides (as shown). Figure 4 As shown), ensure that the strap 3 is smoothly inserted and secured. Several protruding balls 57 are fixed on the fixing roller 56 (as shown). Figure 5 As shown), to increase the friction with the ligament 3 and prevent it from falling off, the first positioning block 51 has positioning holes 54 on both sides, and the second positioning block 52 and the third positioning block 53 have positioning posts 55 fixed on their sides. The positioning posts 55 are inserted into the positioning holes 54. Through the split connection, the first positioning block 51, the second positioning block 52 and the third positioning block 53 fix the ligament 3 in three sections (the middle and the left and right sides), which increases the fixation effect and prevents the ligament 3 from falling off the fixation of the operating table.

[0037] The size of the surgical towel 1 can be a cuboid structure of 180cm*130cm or a convex structure of 90cm*60cm+120cm*130cm for disposable use.

[0038] Positioner 5 has three usage states:

[0039] In the first case, the first positioning block 51, the second positioning block 52, and the third positioning block 53 are integrated and directly set between the two frenulum 3 (the bottom ends of the two frenulum 3 will hang down under the operating table, affecting the rotation scanning of the C-arm CT scanner).

[0040] The second type is where the second positioning block 52 is integrated with the first positioning block 51, and the third positioning block 53 is separate, or the third positioning block 53 is integrated with the first positioning block 51, and the second positioning block 52 is separate, and they are respectively set at the bottom of the intersection of the two straps 3 (where wrinkles are prone to appear in the middle).

[0041] The third type, the first positioning block 51, the second positioning block 52 and the third positioning block 53 are respectively located at the bottom end of one of the two intersecting ties 3, the middle of the intersection, and the bottom end of the other ties 3, without drooping or wrinkles (best).

[0042] Working principle:

[0043] like Figure 1-5 As shown:

[0044] Cut an opening in the surgical towel 1 using scissors or a blade to allow the snap-fit ​​spring 411 to pass through. Secure the ties 3 to the side of the lower fixing block 42. Then, pass the snap-fit ​​spring 411 through the cut opening and engage it inside the snap-fit ​​groove 421 (the snap-fit ​​spring 411 is located inside the snap-fit ​​groove 421, and the bottom of the fixing pin 412 is placed outside the opening on the side of the snap-fit ​​groove 421 and engaged). At the same time, the fixing pin 412 passes through the surgical towel 1 and is inserted into the insert block 422, thereby securing the ties 3 firmly to the surgical towel 1.

[0045] Cover the patient's body with surgical towel 1, ensuring that the opening 2 is aligned with the surgical area;

[0046] Place the bottom ends of the two ties 3 at the bottom of the operating table, and pass the two ties 3 through the slots of the positioner 5, including the first positioning block 51, the second positioning block 52 and the third positioning block 53 respectively. When the ties 3 pass through, the round strip 31 at the bottom of the ties 3 is pushed and squeezed through the two fixed rollers 56. Then adjust the positioner 5 to the appropriate position.

[0047] Pull the second positioning block 52 and the third positioning block 53 so that the second positioning block 52 and the third positioning block 53 are disengaged from the positioning hole 54. Push the second positioning block 52 and the third positioning block 53 to the round strip 31 on the two straps 3 respectively. The round strip 31 can prevent the second positioning block 52 and the third positioning block 53 from going too far through, causing the bottom end of the strap 3 to droop and affect the rotation scanning of the C-arm CT scanner. The convex ball 57 can increase the friction with the strap 3 and prevent the second positioning block 52 and the third positioning block 53 from sliding during use, which would prevent the strap 3 from being restrained and cause the bottom end of the strap 3 to droop.

[0048] After the surgery, the fixation device 4 and the positioning device 5 were removed in sequence, and the surgical towel 1 was taken off.

[0049] Surgical towel 1 is discarded directly, while ties 3, fixation devices 4, and positioning devices 5 are disinfected and reused multiple times.

[0050] In summary:

[0051] This invention securely fixes the straps 3 to both sides of the surgical drape 1 using the fixing component 4, and uses the locator 5 to fix the two straps 3, preventing the bottom ends of the two straps 3 from drooping off the operating table and affecting the rotation scanning of the C-arm CT scanner. The locator 5 avoids the end drooping situation caused by using slip knots and tight knots to fix the two straps 3 (which can also easily lead to entanglement during the rotation scanning of the C-arm CT scanner). At the same time, it avoids the increased workload and cost caused by custom cutting of the surgical drape 1. Only the surgical drape 1 of approximate size needs to be cut, and the straps 3, fixing component 4 and locator 5 need to be installed one by one for use. The straps 3, fixing component 4 and locator 5 can be sterilized and reused multiple times, greatly saving medical supplies. It solves the problem that when using film-type surgical drapes 1 to cover specific parts of the patient, entanglement can easily occur, leading to strong pulling that causes the surgical drape to detach from the patient, causing medical accidents and endangering the patient's life.
