Description

Technical Field

[0001] This invention belongs to the field of medical device technology, and relates to an auxiliary device, specifically a surgical auxiliary device. Background Technology

[0002] Thyroid diseases are common in general surgery. Endoscopic thyroidectomy has been widely performed due to its advantages such as no neck scar, less postoperative pain, and faster recovery. Establishing and maintaining a stable operating space is one of the key steps to a successful endoscopic thyroid surgery.

[0003] Currently, the exposure and maintenance of the operating space in routine endoscopic thyroid surgery mainly rely on various specialized retractor instruments (such as... Figure 1 The gate-shaped retractor 1' and skin retractor 2' shown are used in combination. Specifically, during surgery, the gate-shaped retractor is used to open the subcutaneous tissue and anterior neck muscles to the sides and front from the incision to form an initial cone-shaped operating space; subsequently, when performing delicate operations such as thyroid gland dissection, skin retractors at different angles are used to separate and block the tissue, which requires the scrub nurse and surgical assistant (first assistant) to work continuously at a high intensity.

[0004] However, the aforementioned existing technologies have significant shortcomings in practical applications. Firstly, the alternating use of the gate retractor and skin retractor, angle adjustments, bloodstain removal, and model changes throughout the entire surgical procedure all require the continuous intervention and cooperation of a scrub nurse. This typically necessitates at least two scrub nurses and one surgical assistant to ensure a smooth surgical process (e.g., Figure 2 As shown in the image, this severely consumes valuable medical and nursing human resources. Secondly, scrub nurses and surgical assistants also need to maintain the use of the corresponding surgical instruments for extended periods, making their hands extremely prone to fatigue.

[0005] Therefore, there is an urgent need for a new type of auxiliary device that can reduce the dependence on the continuous high-intensity work of scrub nurses and surgical assistants, reduce the number of medical staff required, and alleviate their workload, so as to optimize the process of endoscopic thyroidectomy and improve surgical efficiency and safety. Summary of the Invention

[0006] To achieve the above-mentioned objectives, the present invention provides a medical auxiliary device for surgical procedures.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is: a surgical medical auxiliary device, comprising: A support frame, the support frame comprising two parallel and spaced-apart support rods and a side end plate installed at either end of the two support rods; A fixed support frame, the fixed support frame including a first support frame root installed at the other end of the two support rods, a first extension connected to the first support frame root via a first adapter, and a first limiting hook formed on the first extension; A movable support frame, the movable support frame including a second support frame root adjustablely mounted on the two support rods, a second extension connected to the second support frame root via a second adapter, and a second limiting hook formed on the second extension and cooperating with the first limiting hook.

[0008] Ideally, the end of the support rod where the side end plate is mounted has a threaded joint with a diameter smaller than that of the support rod, and the side end plate is mounted on the threaded joint by a first nut.

[0009] Furthermore, the movable support frame is adjustablely mounted on the two support rods via a threaded adjusting rod. The threaded adjusting rod includes a rod body with external threads on a portion of its circumferential surface, a rod head formed at the free end of the rod body and adjacent to the external threads, a first connector formed at the other end of the rod body and inserted into the root of the second support frame, and a second nut mounted on the first connector to movably connect the rod body to the root of the second support frame. The external threads are threadedly engaged with the side end plate.

[0010] Furthermore, it also includes: A pull-back assembly, which is adjustablely mounted on the two support rods via another threaded adjusting rod.

[0011] Furthermore, the rear pull assembly includes a slider adjustablely mounted on the two support rods, a connecting strip mounted on the slider, a rear limiting shield plate formed at one end of the connecting strip and located between the first limiting hook and the second limiting hook, and a handle portion formed at the other end of the connecting strip.

[0012] In a preferred embodiment of the present invention, a clearance strip hole is provided at the center of the connecting strip, and two rows of limiting grooves are formed on the upper surface of the connecting strip that connect with the clearance strip hole. A universal lock head is installed on the slider that passes through the clearance strip hole and engages with the limiting groove.

[0013] Specifically, the rear pull assembly further includes a rubber pad, which includes a pad body, a snap-fit ​​protrusion formed on the lower surface of the pad body and cooperating with the limiting groove, and a limiting groove formed on the upper surface of the pad body and cooperating with the universal lock head.

[0014] Specifically, the upper surface of the slider is provided with a spherical receiving cavity, and the universal lock head includes a ball head movably disposed in the spherical receiving cavity, a ball head connecting rod connected to the ball head and passing through the clearance strip hole, and a locking head formed on the upper end of the ball head connecting rod and cooperating with the limiting groove.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The surgical medical auxiliary device of the present invention, through the cooperation of a support frame, a fixed support and a movable support with a specific structure, can create a stable surgical operating space in laparoscopic surgery. This eliminates the need for scrub nurses and surgical assistants to maintain the use of the corresponding surgical instruments for a long time, greatly reducing their workload. The medical auxiliary device can be pre-assembled by the scrub nurse during the surgical preparation period, which can reduce the use of conventional retractor instruments and reduce the number of scrub nurses required to be on-site.

[0020] like Figure 3 The surgical medical aid shown mainly includes a supporting frame 1, a fixed support 2, and a movable support 3. By using the specific structure of the supporting frame 1, the fixed support 2, and the movable support 3, a stable surgical operating space can be created in laparoscopic surgery. This eliminates the need for scrub nurses and surgical assistants to maintain the corresponding surgical instruments for extended periods, greatly reducing their workload. This medical aid can be pre-assembled by the scrub nurse during surgical preparation, which reduces the use of conventional retractor instruments (avoiding the physical exertion of scrub nurses and surgical assistants holding retractors for extended periods) and reduces the need for one scrub nurse to be on-site.

[0021] The support frame 1 includes two parallel and spaced-apart support rods 11 (the ends of the two support rods 11 are aligned) and a side end plate 12 installed at either end of the two support rods 11. Specifically, the end of the support rod 11 where the side end plate 12 is installed has a threaded joint 111 with a diameter smaller than that of the support rod 11. The side end plate 12 is installed on the threaded joint 111 by a first nut 13. At this time, the side end plate 12 has a corresponding insertion hole for the threaded joint 111 (the diameter of the insertion hole is smaller than the diameter of the support rod 11 and slightly larger than the diameter of the threaded joint 111, such as...). Figure 4 As shown), the side end plate 12 can be pressed against the end of the support rod 11 through the insertion hole, and the side end plate 12 is restricted to the end of the support rod 11 by the cooperation of the first nut 13 and the threaded joint 111 (since the first nut 13 can be removed from the threaded joint 111, the side end plate 12 is also detachably installed at the end of the support rod 11).

[0022] The fixed support 2 includes a first support root 21 installed at the other end of the two support rods 11, a first extension 22 connected to the first support root 21 via a first adapter 23, and a first limiting hook 24 formed on the first extension 22. To facilitate detachable assembly between the fixed support 2 and the support rods 11, the other end of the support rods 11 is preferably threaded, and the first support root 21 has a corresponding threaded hole. Thus, the support rods 11 can be installed on the first support root 21 using the threaded connection, at which point the entire fixed support 2 is installed at the other end of the support rods 11 and cannot be moved. The first adapter 23 has an overall convex arc-shaped structure, which ensures the operable area at the surgical site. The first limiting hook 24 is a structure formed by stamping or extruding metal wire (strips), and it is usually formed on the first extension 22 by welding or integral molding, used to act on the laparoscopic surgical incision.

[0023] The movable support 3 is adjustablely mounted on the two support rods 11. It is opposite to and cooperates with the fixed support 2, and its structure is basically the same as that of the fixed support 2. Specifically, the movable support 3 includes a second support root 31 adjustablely mounted on the two support rods 11, a second extension 32 connected to the second support root 31 via a second adapter 33, and a second limiting hook 34 formed on the second extension 32 and cooperating with the first limiting hook 24. The difference is that the second support root 31 has a through hole instead of a threaded hole. In this way, the second support root 31 can be slidably mounted on the two support rods 11, so that the distance between the first limiting hook 24 and the second limiting hook 34 can be increased or decreased, thus enabling the construction and maintenance of laparoscopic surgical incisions of different sizes. In this embodiment, the size of the first limiting hook 24 and the second limiting hook 34 corresponds to the size of the incision in laparoscopic surgery. Due to the operating procedures of laparoscopic surgery, it is usually not necessary to set the size of the first limiting hook 24 and the second limiting hook 34 to different specifications.

[0024] In this embodiment, the movable support 3 is adjustablely mounted on the two support rods 11 via a threaded adjusting rod 4. Specifically, as shown... Figure 5As shown, the threaded adjusting rod 4 includes a rod body 41 with an external thread 43 on a portion of its circumferential surface, a rod head 42 formed at the free end of the rod body 41 and adjacent to the external thread 43, a first connector 44 formed at the other end of the rod body 41 and inserted into the root of the second support 31 (the diameter of the first connector 44 is smaller than the diameter of the rod body 41; a through hole is opened in the middle of the root of the second support 31, the diameter of which is slightly larger than the diameter of the first connector 44 but smaller than the diameter of the rod body 41), and a second nut 45 installed on the first connector 44 to movably connect the rod body 41 and the root of the second support 31 (in this embodiment, an external thread can be provided on the circumferential surface of the first connector 44 so that the second nut 45 can be installed on the first connector 44 through the thread to ensure the movable connection between the rod body 41 and the root of the second support 31). Since the external thread 43 is threadedly engaged with the side end plate 12 (i.e., the middle part of the side end plate 12 has a threaded hole that engages with the external thread 43), the operator's hand acts on the rod head 42 and rotates it, which can realize the movement of the rod body 41 relative to the side end plate 12, thereby driving the root 31 of the second support frame to move on the two support rods 11.

[0025] Some laparoscopic thyroid surgeries are more complex and require larger surgical incisions. Therefore, it is preferable to add a pull-back assembly 5. The pull-back assembly 5 is adjustablely mounted on the two support rods 11 via another threaded adjustment rod 4, so as to cooperate with the first limiting hook 24 and the second limiting hook 34 to create a larger and more stable surgical operating space.

[0026] The rear pull assembly 5 includes a slider 51 adjustablely mounted on two support rods 11 (the slider 51 has two through holes, so that the support rods 11 are inserted into the through holes one by one), a connecting strip 52 mounted on the slider 51, a rear limiting shield plate 54 formed at one end of the connecting strip 52 and located between the first limiting hook 24 and the second limiting hook 34 (the surface of the rear limiting shield plate 54 that contacts the wound is an arc-shaped surface to avoid secondary damage to the wound), and a handle portion 53 formed at the other end of the connecting strip 52 (the connecting strip 52, the rear limiting shield plate 54 and the handle portion 53 are integrally formed). At this time, the position of the rear limiting shield plate 54 cannot be adjusted. In this embodiment, it is generally preferred that the rear limiting shield plate 54 is adjustable, specifically as follows: a clearance strip hole 521 is provided at the center of the connecting strip 52 (the clearance strip hole 521 is perpendicular to the support rod 11), and two rows of limiting grooves 522 are formed on the upper surface of the connecting strip 52, which are connected to the clearance strip hole 521 (the two rows of limiting grooves 522 are arranged one-to-one and symmetrical about the clearance strip hole 521; two adjacent limiting grooves 522 are spaced apart, and the distance between them is the adjustment distance of the rear limiting shield plate 54). A universal lock head 57 is installed on the slider 51, which passes through the clearance strip hole 521 and engages with the limiting groove 522.

[0027] In this embodiment, as Figure 6 As shown, the pull-back assembly 5 also includes a rubber pad 56, which is typically disposable. Other structures of this surgical medical aid are made of conventional metal materials (such as 304 stainless steel, 316 stainless steel, or titanium alloy). These structures can be sterilized and reused, or they can be used disposable. The rubber pad 56 includes a pad body 561, a snap-fit ​​protrusion 562 (also conventionally integrally formed) formed on the lower surface of the pad body 561 and cooperating with the limiting groove 522, and a limiting groove 563 (the bottom surface of the limiting groove 563 is a concave arc surface) formed on the upper surface of the pad body 561 and cooperating with the universal locking head 57. The upper surface of the slider 51 has a spherical receiving cavity, and the universal locking head 57 includes a ball head 571 movably disposed within the spherical receiving cavity (the spherical receiving cavity is slightly larger than the ball head 571, thus ensuring the free rotation or swing of the universal locking head 57, while allowing it to rotate axially (i.e.,...). Figure 6 The ball joint 572, which is connected to the ball head 571 and passes through the clearance strip hole 521, and the locking head 573 formed on the upper end of the ball joint 572 and cooperating with the limiting groove 563, are connected to the ball head 571 and pass through the clearance strip hole 521. When the ball head 571 contacts the upper part of the spherical receiving cavity, the gap between the locking head 573 and the connecting strip 52 is the largest. However, this gap is slightly smaller than the thickness of the gasket body 561. Since the gasket body 561 is made of rubber, after the operator applies force, the locking head 573 can pass over the upper surface of the gasket body 561 and be locked into the limiting groove 563, so that the locking head 573 and the rubber gasket 56 form an elastic lock.

[0028] When this surgical medical aid is used clinically, it is first operated on by the scrub nurse during the surgical preparation phase. Figure 3 Assembly is performed (whether to install the rear pull-up assembly 5 needs to be confirmed with the surgeon in advance). During the operation, the surgeon places the first limiting hook 24 of the fixed support 2 and the second limiting hook 34 of the movable support 3 into both sides of the laparoscopic surgical incision. By rotating the rod head 42, the threaded adjusting rod 4 is driven to move axially relative to the side end plate 12, thereby pushing the movable support 3 to slide smoothly along the support rod 11, so that the distance between the first limiting hook 24 and the second limiting hook 34 gradually increases to the size required for the target surgical operating space. For laparoscopic thyroid surgery that requires a larger exposure area, the slider 51 of the rear pull-up assembly 5 can be additionally installed on the support rod 11. By cooperating with the ball head 571 of the universal lock head 57 and the spherical receiving cavity, the axial position of the rear limiting shield plate 54 can be adjusted within the clearance strip hole 521 of the connecting strip 52. Multi-level locking is achieved by using the snap-fit ​​protrusion 562 of the rubber pad 56 and the limiting groove 522, ultimately creating a larger and more stable surgical operating field.
