Description

Technical Field

[0001] The utility model relates to the technical field of bone cement pushing equipment, in particular to a bone cement pushing equipment capable of multi-angle perfusion. Background Art

[0002] Bone cement is a medical material used in orthopedic surgery, mainly used in fracture repair, spinal surgery and other fields. Its function is to fill bone defects, strengthen bones and promote fracture healing. The bone cement pushing device is a special tool for bone cement injection. It is mainly used in orthopedic surgery to accurately inject bone cement into the patient's bones to strengthen bones or fill bone defects.

[0003] The existing bone cement injection device has a bone cement outlet on the side of the sleeve. During injection, bone cement is injected into the bone from the side of the sleeve. For example, Chinese patent application number CN202122642704.7 discloses a medical dual-modal bone cement injection device, including an injection rod and a sleeve. The outside of the injection rod is provided with an injection rod scale line from bottom to top, and the top of the injection rod is provided with an injection rod handle. The injection rod is provided with a pressure sensing circuit and a temperature sensing circuit. The pressure sensing circuit includes a pressure measurement control system, a pressure display screen and a pressure sensor.

[0004] This push injection device has a bone cement outlet on one side of the sleeve. When the bone cement outlet reaches the position that needs to be filled, bone cement can be injected into one side of the filling position. Since the sleeve is tightly attached to the insertion site after being inserted into the human body, it is difficult for the sleeve to rotate, making it difficult for the device to inject bone cement into the other side of the filling position.

[0008] Preferably, a fixing rod is symmetrically connected to the outer surface of one end of the inner tube close to the handle block.

[0009] Preferably, a groove is provided on the side of the handle block away from the sleeve, a round cover is provided inside the groove, and a through hole is provided through the surface of the round cover.

[0013] Preferably, the round cover is made of PVC.

[0014] Beneficial effects: The utility model provides a bone cement injection device for multi-angle perfusion. It has the following beneficial effects:

[0015] Through the provided sleeve, inner tube and other structures, bone cement is injected into the inner tube, so that the bone cement enters one side of the filling position from the opening. After the filling on this side is completed, the inner tube is rotated so that the hole rotates and corresponds to the opening position on the other side, and bone cement is injected into the inner tube again, so that the bone cement enters the filling position from the opening on this side, thereby completing the filling operation on the other side of the filling position. Compared with the existing technology, by rotating the inner tube so that the hole corresponds to the opening position, bone cement can be output from the corresponding opening position. Since there are multiple openings, the holes can correspond to the opening positions at multiple angles, thereby realizing multi-angle perfusion operations. The inner tube is rotated so that the eccentric hole and the discharge hole positions correspond. At this time, bone cement can enter the filling position from the discharge hole, thereby realizing front end discharge, so that bone cement can be injected from the front end or side of the sleeve.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-6 The utility model provides a technical solution: a bone cement push injection device for multi-angle perfusion, including a sleeve 1, an inner tube 2 is provided inside the sleeve 1, a plurality of openings 3 are penetrated on the outer surface of one end of the sleeve 1, a hole 4 is penetrated on the outer surface of one end of the inner tube 2, and the hole 4 corresponds to the position of the opening 3 on one side, the sleeve 1 is connected to a handle 5 at one end away from the hole 3, the inner tube 2 is penetrated at one end away from the hole 3, and a circular hole 6 is provided on the side of the handle 5 away from the hole 3, and the circular hole 6 is provided inside the circular hole 6. The wall is provided with multiple groups of limit blocks 7, each group of limit blocks 7 consists of two, the outer surface of the inner tube 2 close to the handle block 5 is connected with a stop block 8, the stop block 8 corresponds to the position of the limit block 7, the inner tube 2 away from the handle block 5 is penetrated by an eccentric hole 14, the sleeve 1 away from the handle block 5 is penetrated by a discharge hole 15, the limit block 7 is made of silicone, and the multiple groups of limit blocks 7 respectively correspond to the positions of the openings 3 on one side. When the positions of the openings 3 and the holes 4 correspond, the eccentric holes 14 and the discharge holes 15 are staggered.

[0025] During operation, after the opening 3 and the hole 4 are pierced into the designated position, bone cement is injected into the inner tube 2, and the bone cement flows from the hole 4 to the corresponding opening 3, so that the bone cement is injected into the filling position from the opening 3. After the injection on one side of the filling position is completed, the inner tube 2 is rotated to rotate the hole 4 and correspond to the position of the opening 3 at other angles, and bone cement is continued to be injected into the inner tube 2, so that the bone cement is injected into the filling position from this opening 3, thereby realizing the filling of bone cement from multiple angles. When the angle of the hole 4 corresponds to the angle of the opening 3 on one side, the stop block 8 will be located between the corresponding two limit blocks 7, and the limit block 7 will limit the stop block 8, thereby preventing the inner tube 2 from rotating when it is not subjected to external force, and then keeping the hole 4 at the current angle, which is convenient for subsequent perfusion operations. The inner tube 2 is rotated to make the eccentric hole 14 and the discharge hole 15 correspond to each other. At this time, the positions of the opening 3 and the hole 4 are staggered, and bone cement is injected into the inner tube 2, and the bone cement will be injected into the filling position from the discharge hole 15.

[0026] See also Figure 1-6 The utility model provides a technical solution: the outer surface of one end of the inner tube 2 close to the handle block 5 is symmetrically connected with a fixing rod 9.

[0027] During operation, the inner tube 2 can be rotated by rotating the fixing rod 9 , which makes it more convenient to rotate the inner tube 2 .

[0028] See also Figure 1-6 The utility model provides a technical solution: a groove 10 is provided on the side of the block 5 away from the sleeve 1, a round cover 11 is provided on the inner side of the groove 10, a through hole 13 is opened on the surface of the round cover 11, the outer side of the round cover 11 is in close contact with the groove 10, the fixing rod 9 is located inside the round cover 11, and the axis of the through hole 13 and the inner tube 2 coincide.

[0029] During operation, after the inner tube 2 rotates, the round cover 11 can be inserted into the groove 10. The round cover 11 protects the fixing rod 9, thereby preventing the fixing rod 9 from being accidentally touched and causing the inner tube 2 to rotate. Through the setting of the through hole 13, bone cement can still be injected into the inner tube 2 from the through hole 13 after the round cover 11 is inserted into the groove 10.

[0030] See also Figure 1-6 The utility model provides a technical solution: a rubber ring 12 is connected to the outside of the round cover 11.

[0031] During operation, the friction between the round cover 11 and the groove 10 can be increased by the provision of the rubber ring 12 , so that the round cover 11 is not easily detached after being stuck in the groove 10 .

[0032] See also Figure 1-6 The utility model provides a technical solution: the outer surface of the fixing rod 9 is covered with rubber.

[0033] During operation, the friction force on the surface of the fixing rod 9 can be increased by setting the rubber, which is conducive to rotating the fixing rod 9.

[0034] See also Figure 1-6 The utility model provides a technical solution: the block 5 is provided with anti-slip lines on the side away from the sleeve 1.

[0035] During operation, the anti-slip pattern facilitates gripping of the handle 5 , thereby facilitating control of the insertion angle of the sleeve 1 .

[0036] See also Figure 1-6 The utility model provides a technical solution: the round cover 11 is made of PVC.

[0037] During operation, the round cover 11 made of PVC material has high hardness and is not easily deformed, which is conducive to the long-term use of the round cover 11.

[0038] In summary, after the opening 3 and the hole 4 are inserted into the designated position, bone cement is injected into the inner tube 2, and the bone cement flows from the hole 4 to the corresponding opening 3, so that the bone cement is injected from the opening 3 into the filling position. After the injection is completed on one side of the filling position, the fixing rod 9 is rotated to drive the inner tube 2 to rotate, so that the hole 4 rotates and corresponds to the position of the opening 3 at other angles, and the round cover 11 is inserted into the groove 10. The round cover 11 plays a protective role for the fixing rod 9, thereby preventing the fixing rod 9 from accidentally touching the inner tube 2 and causing the inner tube 2 to rotate. Bone cement is continued to be injected into the inner tube 2, so that the bone cement is injected into the opening 3 from this point. Inject into the filling position, so as to realize the pouring of bone cement into the filling position from multiple angles. When the angle of the hole 4 corresponds to the angle of the opening 3 on one side, the stop block 8 will be located between the corresponding two limit blocks 7. The limit block 7 will limit the stop block 8, thereby preventing the inner tube 2 from rotating when it is not subjected to external force, and then keeping the hole 4 at the current angle, which is convenient for subsequent pouring operations. Rotate the inner tube 2 to make the eccentric hole 14 and the discharge hole 15 correspond to each other. At this time, the positions of the opening 3 and the hole 4 are staggered. Inject bone cement into the inner tube 2, and the bone cement will be injected into the filling position from the discharge hole 15.
