Description

Technical Field

[0001] The utility model belongs to the technical field of medical brackets, and in particular relates to a forearm blood removal position bracket. Background Art

[0002] Radical resection of head and neck tumors often results in a large amount of tissue loss. Currently, the transplantation of autologous vascularized forearm free flaps is still an important means of repairing soft tissue defects. Forearm flaps are also called Chinese flaps. Currently, pneumatic tourniquets are usually used to expel blood before surgery to block blood flow to the distal limbs, creating a "bloodless" clear surgical field of view, reducing perioperative blood loss, and shortening the operation time.

[0003] However, the existing forearm surgical stents cannot perform blood removal at the same time, and the electric blood removal device is large in size and occupies a large area. In addition, flap preparation requires the opening of a second surgical area, and the main and auxiliary tables need to be operated on at the same time, which further reduces the available space. The existing surgical stents and forearm blood removal devices often cause the surgeon and the instrument to block each other, thus affecting the normal surgical process. In addition, the existing forearm surgical stents are mostly integrated on the operating table, with limited height and direction adjustment, and inappropriate fixing devices may also cause the occurrence of soft tissue pressure sores in the operating room. Therefore, a blood removal position stent specifically for forearm flap preparation has become a technical problem that needs to be solved urgently.

[0004] The Chinese patent publication number is CN107485529A, and the patent application is named "Neurosurgery Assisted Monitoring Bed", which includes an operating table, a lying board, a head fixator and a monitoring table; the lying board is fixedly set on the upper surface of the operating table, and the monitoring table is set at one end of the operating table; the head fixator is fixedly set on the lying board; the head fixator includes a bracket and a pressure adjustment device; the bracket includes a forehead support surface and a face support surface, and a gap is set between the forehead support surface and the face support surface; the pressure adjustment device is respectively set on the forehead support surface and the face support surface, and the pressure adjustment device is composed of at least three inflation units, and a pressure sensor and an inflation port are set in the inflation unit, and the switch valve body of the pressure sensor and the inflation port are electrically connected to the monitoring table. This patent application cannot be applied to the support at the arm, and it is not convenient to adjust the height and angle, and it is impossible to perform pressure blood expulsion.

[0028] The utility model is described in detail below in conjunction with the accompanying drawings.

[0029] like Figure 1 As shown, a forearm blood removal position support of the utility model comprises: a support base 4, the top of the support base 4 is connected to a pneumatic lifting rod 7, the side of the pneumatic lifting rod 7 is provided with a pneumatic lifting control rod 6, and the height of the pneumatic lifting rod 7 can be adjusted by pressing the pneumatic lifting control rod 6.

[0030] The top of the pneumatic lifting rod 7 is connected to a universal ball head 13 through a connecting base 12, and the top of the universal ball head 13 is connected to an operating table connecting piece 8. The top of the connecting base 12 is fixedly connected to the universal ball head 13; the bottom of the operating table connecting piece 8 has a mounting groove that matches the universal ball head 13. The universal ball head 13 is connected to the operating table connecting piece 8 in a rolling manner.

[0031] Example 1

[0032] In this embodiment, the support base 4 and the gas pressure lifting rod 7 are both made of stainless steel.

[0033] Specifically, the material connecting the base 12 and the universal ball head 13 is made of stainless steel.

[0034] A through hole is provided in the middle of the side of the operating table connecting member 8, and a universal ball head locking device 9 is installed in the through hole. Specifically, the universal ball head locking device 9 is a threaded rod, and the through hole is a threaded hole.

[0035] Specifically, the universal ball head locking device 9 is made of stainless steel or plastic.

[0036] The top of the operating table connector 8 is connected to an operating table 3 for forearm flap preparation. The sides of the operating table connector 8 are respectively provided with connecting buckles 14, and the sides of the operating table 3 are provided with connecting grooves matching the connecting buckles 14.

[0037] Specifically, the connecting buckle 14 is mortise-jointed with the snap-fit ​​groove.

[0038] The bottom material of the operating table 3 is made of stainless steel, the top of the operating table 3 is covered with sponge, and further, the operating table 3 is wrapped with synthetic leather.

[0039] The operating table 3 is provided with a through hole extending from top to bottom, and a pneumatic tourniquet 2 is provided on the operating table 3. One end of the pneumatic tourniquet 2 is fixed on the operating table 3, and the other end passes through the through hole of the operating table 3 and out of the bottom of the operating table 3. A mounting hole connected to the through hole is provided on the side of the operating table 3, and the mounting hole has a thread. A pneumatic tourniquet locking device 10 is installed in the mounting hole. Specifically, the pneumatic tourniquet locking device 10 is a threaded rod.

[0040] The pneumatic tourniquet locking device 10 is used to lock the pneumatic tourniquet 2, so as to adjust the size of the tourniquet according to different arm circumferences. Specifically, the pneumatic tourniquet locking device 10 is made of stainless steel or plastic.

The central control device 5 has a power supply and a backup energy storage power supply, which can supply the equipment to operate during a power outage. The central control device 5 is computer controlled. When the pressure reaches the set value, it automatically stops pumping air to the air pressure tourniquet 2 and maintains a constant pressure. When the air pressure tourniquet 2 leaks, it can automatically replenish air to the set pressure. During the operation, the pressure can be increased or decreased at any time and the timing can be automatically increased or decreased.

[0045] Example 2

[0046] The utility model is a forearm exsanguination position support. When in use, the operating table 3 and the connecting base 12 are installed by connecting the buckle 14 before the operation. The forearm is disinfected and placed on the operating table 3. The operating table 3 is adjusted to a suitable height and angle by the pneumatic lifting rod 7 and the universal ball head 13, and the universal ball head 13 is fixed by the universal ball head locking device 9. The pneumatic tourniquet 2 is installed, and the appropriate tightness is adjusted. The inflation motor 11 is controlled by the central control device 5 to inflate and exsanguinate through the inflation pipeline 1. After setting the exsanguination time, the operation is performed. After the operation is completed, when the preset time is reached, the pneumatic tourniquet 2 is deflated and the exsanguination is completed.
