Description

Technical Field

[0001] This utility model relates to the field of surgical auxiliary instruments technology, and in particular to an intraoperative adjustable forearm suspension device, which is also a multifunctional anesthesia head frame. Background Technology

[0002] In surgeries such as those involving mediastinal tumors in thoracic surgery, right hepatic tumors in hepatobiliary surgery, and orthopedic procedures, patients are typically placed on their side on the operating table in a supine position with their chest and back tilted upwards. This position, with the affected side facing upwards and the upper arm raised, facilitates surgical manipulation. This supine position effectively exposes the surgical site, reduces pressure on the lungs and mediastinal organs, and promotes blood flow back to the heart. When performing surgery in this supine position, the upper arm is usually positioned at an angle around the head and neck to expose the surgical field while protecting the axillary nerve. Specific postures are as follows: Figure 6 As shown.

[0003] In existing technologies, patients undergoing surgery lack voluntary control due to the effects of anesthesia and are unable to maintain their arm posture independently. Common practices include medical staff using soft pads under the armpits and neck to provide support, or using small tables to support the arms and maintain posture. However, these methods are prone to failure due to deformation of the soft pads, or obstruction of the medical staff's field of vision by the tables, causing inconvenience to the surgical process.

[0004] Therefore, existing technologies still need to be improved and developed. Utility Model Content

If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0033] In existing technologies, patients undergoing surgery lack voluntary control due to the effects of anesthesia and are unable to maintain their arm posture independently. Common practices include medical staff using soft pads under the armpits and neck to provide support, or using small tables to support the arms and maintain posture. However, these methods are prone to failure due to deformation of the soft pads, or obstruction of the medical staff's field of vision by the tables, causing inconvenience to the surgical process.

[0034] In view of the above-mentioned problems in the prior art, this utility model provides an intraoperative adjustable forearm suspension device, such as... Figure 1 and Figure 2 As shown, the intraoperative adjustable forearm suspension device includes: a head frame 100, on which a limiting groove 110 is provided; a lifting assembly 200, which includes a belt body 210 and a limiting ring 220. The belt body 210 includes a connecting end 211 fixedly connected to the limiting ring 220 and an mounting end 212 facing away from the limiting ring 220. The mounting end 212 passes through the limiting ring 220 to form a sleeve 213, which is used to fit the patient's arm. The mounting end 212, which passes through the limiting ring 220, is folded back and detachably connected to one side of the connecting end 211, forming a buckle 214 fitted on the limiting groove 110.

[0035] This invention utilizes the existing anesthesia head frame configured on the operating table. A limiting groove 110 and a suitable lifting assembly 200 are set on the anesthesia head frame. The mounting end 212 of the belt body 210 passes through the limiting ring 220 to form a sleeve 213 for fitting the patient's arm. The mounting end 212 of the belt body 210 passes through the limiting ring 220 and combines with the connecting end 211 of the belt body 210 to form a buckle 214, which can cooperate with the limiting groove 110 to form a stable suspension of the patient's arm. This invention is simple to operate and convenient to use. It can reduce the obstruction of the operating field of medical staff and maintain the patient's chest and back in a tilted supine position with the arm in a supine position.

[0036] In the above embodiments, such as Figure 1 and Figure 2 As shown, the main body of the intraoperative adjustable forearm suspension device of this utility model consists of a head frame rod 100 and a lifting assembly 200. The head frame rod 100 is used in conjunction with the anesthesia head frame set on the operating table in the prior art. At the same time, in order to realize the cooperation between the head frame rod 100 and the lifting assembly 200, a limiting groove 110 is provided on the head frame rod 100 in this embodiment. In the prior art, the anesthesia support head frame is used to support the sterile area and strictly distinguish the sterile area from the sterile area. The setting of the limiting groove 110 on the anesthesia head frame does not affect its traditional function.

[0037] The structure of the hoisting assembly 200 is as follows: Figure 2 As shown, it is specifically composed of a belt body 210 and a limiting ring 220. In order to facilitate the differentiation of the ends of the belt body 210 and the description of the use of the belt body 210, the two ends of the belt body 210 are named the connecting end 211 and the mounting end 212 in this embodiment. The connecting end 211 of the belt body 210 is fixedly connected to the limiting ring 220, and the mounting end 212 is a free end, which is used to form a sleeve with the patient's arm and to form a combination with the head frame rod 100.

[0038] Specifically, such as Figure 2 As shown, in actual use, the mounting end 212 is reversed and passes through the limiting ring 220, so that the part of the belt body 210 near the connecting end 211 forms an annular sleeve 213. This sleeve 213 can fit the patient's arm in actual use. Furthermore, the mounting end 212 after passing through the limiting ring 220 is folded back at a certain length and forms a detachable connection with one side of the mounting end 212 of the belt body 210. The part of the belt body 210 corresponding to the mounting end 212 passing through the limiting ring 220 forms a buckle 214. This buckle 214 can be fitted with the head frame rod 100 and placed at the position of the corresponding limiting groove 110, thereby forming a suspension for the patient's arm. Since the position is restricted by the limiting groove 110, slippage during surgery can be avoided. In actual use, the buckle 214 also plays a role in the direction of rotation so that the angle of the sleeve 213 fitted on the patient's arm corresponds to the angle of the patient's arm.

[0039] Furthermore, to facilitate the application of the strap to the patient's arm, in this embodiment, the strap 210 is made of a flexible material. The flexible material of the strap 210 facilitates the application of the strap to the patient's arm and avoids pressure on the patient's skin. Meanwhile, to ensure the stability of the patient's arm, the limiting ring 220 is made of a rigid material. The rigid material of the limiting ring 220 ensures the support strength of the strap 210 and the stability of the patient's arm.

[0040] In addition, such as Figure 3 As shown, in order to facilitate the smooth detachable connection between the mounting end 212 and the connecting end 211 after the sleeve 213 is formed on the mounting end 212 to cover the patient's arm, in this embodiment, guide portions 215 are respectively provided on both sides of the mounting end 212. The guide portions 215 are set along a predetermined arc. The setting of the guide portions 215 can facilitate the mounting end 212 to fold back along the predetermined arc after passing through the limiting ring 220, and smoothly form a detachable connection with the connecting end 211.

[0041] In actual use, medical staff can first pass the installation end 212 of the hoisting component 200 through the limiting ring 220 to form a sleeve 213 to put on the patient's arm. Then, the installation end 212 is folded back along the guide part 215 and detachably connected with the connecting end 211. The hoisting component 200 is then engaged with the limiting groove 110 of the head frame rod 100 through the buckle 214 to hoist the patient's arm. The operation is simple. At the same time, due to the engagement of the buckle 214 and the limiting groove 110, the patient's arm can be prevented from slipping during the operation, reducing the obstruction of the medical staff's field of vision and maintaining the patient's chest and back in a tilted supine position with the arm in place.

[0042] Specifically, to achieve a detachable connection between the mounting end 212 and the connecting end 211 of the belt body 210, such as Figure 3 As shown, in a specific embodiment of this utility model, a first adhesive member 240 can be provided on one side of the mounting end 212, and correspondingly, a second adhesive member is provided on the side of the connecting end 211 opposite to the first adhesive member 240. The first adhesive member 240 and the second adhesive member are detachably and securely connected, thereby facilitating medical personnel to quickly and securely install the lifting assembly 200 on the head frame rod 100, and also making it easy to disassemble and adjust it when needed. This design not only improves the efficiency of surgical operations, but also ensures the comfort and safety of patients during the surgical process. In addition, the first adhesive member 240 and the second adhesive member are preferably two parts of Velcro, because Velcro has the characteristics of strong adhesion, easy disassembly and reusability, which is very suitable for surgical auxiliary instruments that require frequent adjustments.

[0043] To facilitate observation of the blood vessel condition in the patient's wrist, such as Figure 2 and Figure 3 As shown, in this embodiment, an observation section 230 is also provided on the strap 210. The observation section 230 is a transparent observation section 230. The transparent observation section 230 allows medical personnel to directly observe the blood vessel condition of the patient's wrist without removing the lifting assembly 200. This is of great significance for procedures such as administering intravenous fluids or monitoring blood pressure during surgery. The transparent observation section 230 can be a window made of transparent material or a portion of the strap 210 made of transparent material. It ensures that medical personnel can clearly see the skin and blood vessels of the patient's wrist, thereby improving the efficiency and safety of the surgery.

[0044] In practical applications, the size and position of the transparent observation section 230 can be designed according to specific needs to ensure that observation requirements are met without affecting the overall structure and function of the hoisting assembly 200. At the same time, the material of the transparent observation section 230 needs to have good transparency and durability to ensure its long-term reliability and clarity.

[0045] In the second embodiment of this utility model, to further adapt to the different arm sizes of patients and to facilitate medical staff in fine-tuning the posture of the patient's arm according to surgical needs, such as... Figure 4 and Figure 5 As shown, the strap body 210 can be configured to include a first strap 201 and a second strap 202 that are separately disposed from each other. The connecting ends 211 of the first strap 201 and the second strap 202 are fixedly connected to the limiting ring 220, while the mounting ends 212 of the first strap 201 and the second strap 202 are separately disposed. This design makes the lifting assembly 200 more flexible in installation and use, and can be adjusted according to the arm size and surgical needs of different patients, improving the adaptability and comfort of the surgery.

[0046] Specifically, such as Figure 4 and Figure 5 As shown, the first strap 201 and the second strap 202 can be connected to the mounting end 212 and the connecting end 211 via Velcro, buckles, or other detachable connection methods. Medical personnel can adjust the tightness of the first strap 201 and the second strap 202 according to the thickness of the patient's arm and the needs of the surgery to ensure that the patient's arm remains stable and comfortable during the operation. Furthermore, since the first strap 201 and the second strap 202 are separate, they can be adjusted independently, further improving the flexibility and applicability of the lifting assembly 200.

[0047] Furthermore, in a preferred embodiment of this invention, the first strap 201 can also be a transparent strap. In actual use, the first strap 201 is fitted onto the patient's wrist. The transparent strap not only facilitates medical staff's observation of the blood vessels in the patient's wrist but also enhances the aesthetics and modernity of the lifting assembly 200. The transparent strap can be made of transparent materials, such as transparent plastic or transparent rubber, which possesses good flexibility and durability, adapting to different arm sizes and surgical needs. Simultaneously, the transparency of the strap makes the lifting assembly 200 more concise and aesthetically pleasing overall, improving the cleanliness and comfort of the operating room.

[0048] In another possible embodiment of this utility model, such as Figure 1 As shown, since patients may have different chest and back tilt positions during surgery, meaning the surgical site may be on the left or right side, to address the different arm sling positions for different patient orientations, this embodiment also includes two limiting grooves 110 at each end of the headrest rod 100. It is important to note that the two limiting grooves 110 should be located at both ends of the horizontal section of the headrest rod 100, corresponding to the sides of the operating table. This allows medical staff to flexibly adjust the arm sling position according to the patient's surgical needs, adapting to different surgical scenarios. This design not only improves surgical flexibility but also further ensures patient comfort and safety during the procedure.

[0049] In one specific implementation, such as Figure 1 As shown, the headrest rod 100 also includes a slide rail 130 fixedly mounted on one side of the operating table, and a mounting base 140 slidably connected to the slide rail 130. The headrest rod 100 is detachably mounted on the mounting base 140. In actual use, medical staff can adjust the position of the mounting base 140 on the slide rail 130 according to actual needs, thereby adjusting the relative position between the headrest rod 100 and the patient. The headrest rod 100 can also be rotated to adjust the relative angle between the headrest rod 100 and the operating table, so that the direction of the sleeve 213 in the lifting assembly 200 corresponds to or is close to the direction of the patient's arm, thereby reducing the amount of torsion of the belt 210. In addition, the actual function of the headrest rod 100 can be switched at different stages of the operation. In this embodiment, the mounting base 140 and the slide rail 130 are preferably configured as a damped sliding connection to facilitate medical staff to adjust and fix the actual position of the mounting base 140.

[0050] Furthermore, such as Figure 1As shown, the mounting base 140 also includes a vertically oriented mounting hole 141 for inserting the headrest rod 100. A locking handle 142 is provided on one side of the mounting base 140, corresponding horizontally to the mounting hole 141. A locking rod inside the locking handle 142 is rotatably connected to the mounting base 140, and the end of the locking rod penetrates the mounting hole 141. Correspondingly, the headrest rod 100 includes a bent portion 120, which is functionally related to the headrest rod 100. The headrest is set at a vertical angle. During actual installation, one end of the bent part 120 is inserted into the mounting hole 141. By rotating the locking handle 142, the locking rod and the bent part 120 can abut against each other at the corresponding position in the mounting hole 141, thereby achieving a fixed connection between the headrest rod 100 and the mounting base 140. This structure allows for height adjustment of the headrest rod 100 and adjustment of the relative angle between the headrest rod 100 and the operating table, thus meeting different surgical operation needs at different stages of the operation. For example, at the beginning of the operation, medical staff can adjust the headrest rod 100 to a lower position to facilitate anesthesia; during the operation, medical staff can adjust the headrest rod 100 to a higher position and align its orientation with the patient's arm to suspend the patient's arm. This avoids obstruction of the surgical field of vision by the headrest rod 100 and allows for suspension of the patient's arm using an adjustable forearm sling during the operation, improving the flexibility and safety of the operation.

[0051] Based on the above embodiments, the actual use of the adjustable forearm suspension device of this utility model is as follows:

[0052] Before the actual surgery, medical staff first fix the headrest rod 100 to the slide rail 130 of the operating table via the mounting base 140, and adjust the height and angle of the headrest rod 100 to adapt to the patient's tilted chest and back position, arm position, and surgical site. Then, the medical staff pass the mounting end 212 of the lifting assembly 200 through the limiting ring 220 to form a sleeve 213 structure, and fit the patient's arm into the sleeve 213. Next, the medical staff fold the mounting end 212 back along the guide portion 215, and use the first adhesive piece 240 and the second adhesive piece (such as Velcro) to fix the mounting end 212 to the connecting end 211, thus forming a stable buckle 214 structure. This buckle 214 structure is then placed in the limiting groove 110 of the headrest rod 100 to achieve stable suspension of the patient's arm.

[0053] During the surgery, medical staff can adjust the height and angle of the headframe 100 or the tightness of the suspension assembly 200 at any time according to the progress of the surgery and the needs of the patient's arm. The transparent observation section 230 allows medical staff to directly observe the blood vessels in the patient's wrist without removing the suspension assembly 200, which is crucial for procedures such as intravenous infusion and blood pressure monitoring. Meanwhile, the separate design of the first strap 201 and the second strap 202 allows the suspension assembly 200 to adapt to arms of different sizes, improving the adaptability and comfort of the surgery.

[0054] After the surgery, medical staff can easily disassemble the sling assembly 200, remove it from the head frame rod 100, and perform necessary cleaning and disinfection for future use. Throughout the process, this novel intraoperative adjustable forearm sling not only simplifies surgical procedures and improves surgical efficiency, but also ensures patient comfort and safety during the procedure, demonstrating significant clinical application value.

[0055] Based on the above embodiments, this utility model also provides a multifunctional anesthesia head frame, which includes the intraoperative adjustable forearm suspension device in the above embodiments. The intraoperative adjustable forearm suspension device includes: a head frame rod with a limiting groove; a lifting assembly, which includes a belt and a limiting ring. The belt includes a connecting end fixedly connected to the limiting ring and an mounting end facing away from the limiting ring. The mounting end passes through the limiting ring to form a sleeve, which is used to fit the patient's arm. The mounting end, which passes through the limiting ring, can be detachably connected to one side of the connecting end after being folded back, forming a buckle fitted on the limiting groove. This invention utilizes the existing anesthesia head frame configured on the operating table. A limiting groove and a suitable lifting assembly are provided on the anesthesia head frame. The mounting end of the strap passes through the limiting ring to form a sleeve that fits over the patient's arm. The mounting end of the strap, passing through the limiting ring, combines with the connecting end of the strap to form a buckle, which can cooperate with the limiting groove to provide stable support for the patient's arm. This invention is simple to operate and convenient to use, reducing obstruction to the operating field of medical staff and maintaining the patient's arm in a tilted supine position.
