Description

Technical Field

[0001] The invention belongs to the technical field of medical surgical equipment, and in particular relates to a multi-angle surgical support arm. Background Art

[0002] The surgical support arm is a surgical auxiliary device installed on the hospital operating table. The patient's upper limbs can be placed on it during surgery to facilitate the smooth progress of subsequent surgery.

[0003] The surgical process is a very complex operation process. Generally speaking, the patient's limbs must be properly fixed first to prevent them from moving and changing position during surgery. The second is the direction and angle of arm placement, which will directly affect the doctor's surgical posture, surgical field exposure, and surgical speed, thereby affecting the surgical effect. At the same time, it is also beneficial for the anesthesiologist to observe the effectiveness of the surgical anesthesia monitoring facilities at any time.

[0004] The existing technology basically adopts an ordinary lifting operating table, supplemented with a support plate or baffle that crosses the operating table, and the patient's upper limbs are placed on the support plate or the baffle is used to limit the movement of the arm. During the operation, a surgical assistant is required to continuously support and fix the patient's arm or wrist. This type of support plate not only has only one support surface for the patient's upper limbs, and cannot provide multi-angle and multi-directional support and protection, but also cannot be used for patients with different upper limbs and different circumferences, and has poor adaptability.

[0005] Based on this, the applicant considered designing a multi-angle surgical support arm. Summary of the invention

[0006] In view of the above problems, the present invention provides a multi-angle surgical support arm stand that overcomes the above problems or at least partially solves the above problems. The technical solution is as follows:

[0007] A multi-angle surgical support arm frame comprises a bed body, a fixed frame, a transverse rotation mechanism, a first support arm and a second support arm, wherein the fixed frame is fixedly mounted on the bottom of the side wall of the bed body, the transverse rotation mechanism is fixedly connected to the fixed frame and is located on the outer side of the side wall of the bed body, the first support arm and the second support arm are both in the shape of an elongated strip, the first support arm is connected above the transverse rotation mechanism, the second support arm is connected to the first support arm and is arranged opposite to the first support arm, a load-bearing cavity opening upward is formed between the second support arm and the first support arm, and the second support arm can move relative to the first support arm to adjust the width of the load-bearing cavity, and the transverse rotation mechanism can drive the first support arm and the second support arm to rotate transversely at the same time.

[0008] Compared with the prior art, the multi-angle surgical support arm of the present invention has the following advantages:

[0009] By arranging the bed body, the fixing frame, the transverse rotation mechanism, the first support arm and the second support arm, the first support arm and the second support arm can be laterally rotated under the drive of the transverse rotation mechanism, and the first support arm and the second support arm can also move relatively to adjust the width of the bearing cavity therein, thereby realizing the support and protection of the patient's arm at multiple angles and in multiple directions, and it is universal for different parts of the arm and different circumferences, and has better adaptability.

[0010] The above-mentioned multi-angle surgical support arm has the advantages of simple structure and easy implementation. It is suitable for installation and use on an existing operating table or during surgery. It has low cost of use and can improve benefits. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Compared with the prior art, the multi-angle surgical support arm of the present invention has the following advantages:

[0030] By setting the bed body 100, the fixing frame 200, the transverse rotation mechanism, the first support arm and the second support arm, the first support arm and the second support arm can be laterally rotated under the drive of the transverse rotation mechanism, and the first support arm and the second support arm can also move relatively to adjust the width of the bearing cavity therein, thereby achieving multi-angle and multi-directional support and protection for the patient's arm, and it is universal for different parts of the arm and different circumferences, and has better adaptability.

[0031] The above-mentioned multi-angle surgical support arm has the advantages of simple structure and easy implementation. It is suitable for installation and use on an existing operating table or during surgery. It has low cost of use and can improve benefits.

[0033] In this way, by providing the supporting platform 310 and the first motor 320 , the first motor 320 can drive the first support arm and the second support arm to rotate, and the rotating structure is relatively stable and reliable.

[0034] In this embodiment, Figure 1-8 As shown, the first support arm includes a base plate 410 and a first side plate 420, the first side plate 420 is vertically connected to the inner edge of the base plate 410, the base plate 410 includes a first end 411 and a second end 412 relative to each other, the rotating shaft of the first motor 320 is transmission-connected to the first end 411 of the base plate 410, the second end 412 is a free end, and the second support arm is transmission-connected to the base plate 410 and can move relative to the first side plate 420.

[0035] In this way, by setting the bottom plate 410 and the first side plate 420, the bottom plate 410 can support the arm, and the first side plate 420 can limit and protect on both sides of the side plate, and the protection effect is better.

[0036] In this embodiment, Figure 1-8 As shown, the second support arm includes a transmission square column 510 and a second side plate 520, the transmission square column 510 includes a relative connecting end and a transmission end, the second side plate 520 is vertically connected to the connecting end, a transmission cavity is provided in the base plate 410, the transmission cavity passes through the outer edge of the base plate 410, the transmission end of the transmission square column 510 can be inserted into the transmission cavity from the outer edge of the base plate 410, a threaded cavity is provided in the transmission square column 510, the threaded cavity passes through the end face of the transmission end, a second motor is provided in the transmission cavity near the inner edge of the base plate 410, a transmission shaft consistent with the length direction of the transmission cavity is also provided in the transmission cavity, one end of the transmission shaft is connected to the rotating shaft of the second motor, and the other end can extend into the threaded cavity and cooperate with the threaded transmission of the threaded cavity, so that the transmission shaft can drive the second side plate 520 to move relative to the first side plate 420.

[0037] In this way, by setting up the transmission square column 510 and the second side plate 520, the second support arm can be moved relative to the first support arm. The moving structure is relatively simple and the transmission is efficient, so that the width of the bearing cavity between the first side plate 420 and the second side plate 520 can be adjusted, and the adaptability is better.

[0038] During implementation, threads are arranged on the transmission shaft and in the threaded cavity.

[0039] During implementation, the bearing cavity is a cavity formed between the first side plate 420 and the second side plate 520 .

[0040] In this embodiment, Figure 1-8 As shown, inner grooves are provided on the opposite inner sides of the first side plate 420 and the second side plate 520 .

[0041] In this way, by setting the inner groove, the limiting and protection on both sides of the patient's arm after being placed in the load-bearing cavity can provide larger space and higher comfort.

[0042] In this embodiment, Figure 1-8 As shown, a baffle 600 is fixedly connected to the side wall of the first side plate 420 close to the bed body 100 , and the length direction of the baffle 600 is consistent with the length direction of the first side plate 420 .
