[0020] See attached Figure 1 and Figure 2 The utility model discloses a wrist arthroscopy operating table, comprising an operating table 1, an adjustable support assembly 2 and a traction assembly 3 (the finger sleeve of the traction assembly is not shown in the figure), the adjustable support assembly 2 comprises a column member 21 and a crossbeam member 22, the operating table 1 has a shelf 11 for the patient's arm to rest on and an installation station 1 for fixing the column member 21, the bottom of the column member 21 is fixedly installed on the installation station 1 of the operating table 1, and the top of the column member 21 is connected to the crossbeam member 22, the specific adjustable structural forms of the column member 21 and the crossbeam member 22, and the traction assembly 3 are conventional technologies in the field, so the specific structures of the column member 21, the crossbeam member 22 and the traction assembly 3 are not repeated here. The operating table 1 is equipped with a mounting plate 11 for fixing the patient's arm. The arm fixing member is fixed on the shelf surface 11 of the operating table 1. One side of the operating table 1 along the longitudinal direction of the shelf surface 11 is the inner side a for the patient's arm to extend into. The shelf surface 11 is provided with an arc-shaped shallow concave surface near the inner side a. The shallow concave surface provides a certain positioning for the patient's arm. The other side of the operating table 1 opposite to the inner side a is the outer side b. The outer side b is usually facing the doctor. In order to solve the problem that the traditional column member is installed in the horizontal center position of the outer side of the operating table, which causes interference with the doctor's surgery (including obstruction of the surgical line of sight and the operating position), the inner side a of the operating table 1 is provided with a mounting position I on the left and right sides of the shelf surface 11, and the bottom of the column member 21 is provided with a mounting base 211, and the mounting base 211 can be detachably mounted on the mounting position I. When in use, the adjustable bracket assembly 2 is fixed on the corresponding installation station I according to the actual arm position (left hand or right hand) of different patients for surgery. During the surgical operation, the column component 21 corresponds to the patient's armpit position, so that the column component 21 is arranged obliquely in front of the physician to achieve effective avoidance. The patient's arm can be fully exposed when fixed to the wrist arthroscopy operating table, which facilitates the physician's surgical operation and improves the surgical efficiency.
[0021] Furthermore, the operating table 1 is fixed with a T-shaped cross-sectional T-seat 12 located at the installation station 1. The mounting base 211 of the column member 21 is provided with a T-slot 212 and a locking member 213. The locking member 213 is typically a hand-tightening bolt. The T-slot 212 of the mounting base 211 is adapted to fit within the T-seat 12 and is locked and secured to the T-seat 12 via the locking member 213. After the mounting base 211 is slidably mounted onto the T-seat via the T-slot 212, the hand-tightening bolt is tightened to lock the mounting base 211 to the T-seat 12. Of course, those skilled in the art, guided by the present invention, may also find other existing mounting solutions for achieving detachable mounting of the column member. However, the above-disclosed embodiment has the advantages of simple structure, easy operation, secure and reliable fixation, and ease of high-temperature sterilization. The T-seat 12 is extended a certain length longitudinally along the resting table 11, and the mounting base 211 can slide along the T-seat 12 to adjust its position. The position of the adjustable mounting frame assembly can be adjusted to better suit the use of patients of different body sizes.
[0022] like Figures 1-3 As shown, as another embodiment of the present invention, in order to solve the problem of inconvenience in sterilizing the traditional textile cloth arm restraint member, the arm fixing member is replaced with a flexible metal restraint belt 4 suitable for high-temperature sterilization. The flexible metal restraint belt 4 can be a metal belt woven with metal wire or a chain link type. The flexible metal restraint belt 4 can be directly purchased from the market according to the size requirements. On the operating table 1, on both sides of the shelf 11, there are high-temperature sterilization-resistant belt fixing seats 5. After the flexible metal restraint belt 4 spans the shelf 11, its two ends are fixed to the two belt fixing seats 5 respectively. At least one end of the flexible metal restraint belt 4 is adjustable and set on the corresponding belt fixing seat 5 to adjust the restraining length of the flexible metal restraint belt 4.
[0023] As a preferred mode, the adjustable flexible metal restraint belt 4 is reeled, which has the advantage of convenient operation. Specifically, a belt reeling mechanism is arranged on one of the belt fixing seats 5. For better illustration of the improved technology, the belt fixing seat with the belt reeling mechanism is referred to as belt fixing seat A, and the flexible metal restraint belt 4 is fixed on the other belt fixing seat 5 by a simple clamping or hanging method. The belt reeling mechanism comprises a reeling shaft 61, a reeling operation hand wheel 62 and a shaft locking assembly 63. The belt fixing seat A is provided with a belt reeling cavity 51 with an external communication port. The reeling shaft 61 is rotatably arranged on the belt fixing seat A. The reeling shaft 61 has a belt reeling shaft body 611 corresponding to the belt reeling cavity 51. The flexible metal restraint belt 4 is inserted into the belt reeling cavity 51 through the external communication port and fixed on the belt reeling shaft body 611. The flexible metal restraint belt 4 and the belt reeling shaft body 611 can be fixed by clamping or welding. The reeling operation hand wheel 62 drives the reeling shaft 61 to rotate to reel or release the flexible metal restraint belt 4. The shaft locking assembly 63 locks and unlocks the reeling shaft 61 on the belt fixing seat A. The reeling operation hand wheel is arranged on the outer side of the belt fixing seat A corresponding to the operating table plate, so as to facilitate the operation of the doctor. In this way, the flexible metal restraint belt can be reeled to reliably constrain the patient's arm on the operating table plate. The operation is simple and convenient.
[0024] In the embodiment, the shaft locking assembly 63 comprises a locking gear 631, a locking block 632, a control knob 633 and an unlocking spring 634. The locking gear 631 is installed on the reeling shaft 61. The locking block 632 is slidingly fitted on the corresponding belt fixing seat (belt fixing seat A). The locking block 632 is provided with a locking piece 635 facing the locking gear 631. The locking piece 635 is correspondingly fitted with the teeth of the locking gear 631. The locking piece 635 is engaged into the tooth groove of the locking gear 631 to lock the locking gear, i.e. to lock the reeling shaft 61. The unlocking spring 634 abuts on the locking block 632 and drives the locking piece 635 on the locking block 632 to disengage from the locking gear 631. The control knob 633 is threadedly screwed on the belt fixing seat A. One end of the control knob 633 abuts on the locking block 632. The control knob 633 controls the locking piece 635 on the locking block 632 to engage into and disengage from the tooth groove of the locking gear 631. Of course, the specific structure of the shaft locking assembly can also be a ratchet gear assembly with one-way locking function. The ratchet teeth can disengage from the ratchet wheel to completely release the ratchet wheel. Alternatively, a brake pad structure can be used.
[0025] As a preferred mode of the utility model, at least one of the belt fixing seat 5 is detachably mounted on the operating table plate 1 through the quick release structure to constitute the flexible metal restraint belt 4, and the at least one end of the flexible metal restraint belt 4 can be detached from the operating table plate 1 to open the space above the rest table top 11. In this way, the space above the rest table top 11 of the operating table plate can be opened, and the patient's arm can be conveniently placed in and removed from the rest table top 11.
[0026] As a preferred mode, the quick release structure comprises a 7-shaped convex rail 13 fixed on the operating table plate 1 and a 7-shaped groove 52 provided at the bottom of the corresponding belt fixing seat 5. The top end lateral protrusion 131 of the 7-shaped convex rail 13 protrudes towards one side of the rest table top 11. The 7-shaped groove 52 has a lateral slot 521 that can be fitted into the top end lateral protrusion 131. The bottom end opening of the 7-shaped groove 52 on the bottom wall of the corresponding belt fixing seat 5 is an assembly opening 522 that can be buckled on or detached from the top of the 7-shaped convex rail 13. Thus, the belt fixing seat 5 can be directly buckled and removed along the space above the operating table plate 1, which is simple and convenient to operate. A clamping bolt 53 is provided on the corresponding belt fixing seat 5. The clamping bolt 53 is provided on the side opposite to the position of the lateral slot 521 on the 7-shaped groove 52. The clamping bolt 53 has a locking end that extends into the 7-shaped groove 52 and can be clamped on the 7-shaped convex rail 13. During installation, the clamping bolt is loosened, the locking end of the clamping bolt avoids the 7-shaped convex rail, the belt fixing seat is directly buckled onto the 7-shaped convex rail through the assembly opening, the belt fixing seat is moved laterally, the lateral protrusion is inserted into the lateral slot, the locking end of the clamping bolt is screwed into the 7-shaped groove and clamped on the 7-shaped convex rail, and the belt fixing seat is fixed on the operating table plate. During disassembly, the direction is operated to directly open the space above the rest table top, and the patient's arm is placed on the operating table plate. The quick release structure is simple in structure, and the belt fixing seat is fixed firmly and reliably.
[0027] Due to the difference in arm length of different patients, it is necessary to adjust the position of the flexible metal restraint belt to better adapt to the arm fixation of different patients. In view of the above quick release structure design, the adjustable setting of the belt fixing seat can be conveniently and reliably realized. Therefore, both of the belt fixing seats 5 are provided with quick release structures, and both of the belt fixing seats 5 can slide along the corresponding 7-shaped convex rail 13 to realize the adjustable setting of the position of the belt fixing seat 5 on the operating table plate 1. The symmetrical structure design is also relatively convenient for processing. Moreover, under the above design, the T-shaped seat 12 design can be matched with each other to realize more compact overall structure design. Figure 2 As shown in the figure, the 7-shaped convex rail 13 and the T-shaped seat 12 are directly connected and integrated.
[0028] The wrist arthroscopy operating table of the utility model realizes more comprehensive high-temperature disinfection requirement while conveniently operating. And because the operating table plate is configured with structures such as a fixing seat, a winding adjusting mechanism and a T-shaped seat, the counterweight of the operating table plate is improved, so that the operating table plate itself can be designed thinner. The above embodiments are only used for illustrating the utility model, and are not a limitation on the utility model. Under the guidance of the utility model, the person skilled in the art can also make corresponding deformation or modification on the corresponding structure of the utility model in combination with the existing technical knowledge, so that all equivalent technical solutions fall within the protection scope of the utility model.
