Description

Technical Field

[0001] The present invention relates to an external fixation bracket used in the clinical diagnosis and treatment process, and particularly to a puncture needle fixation bracket. Background Art

[0002] Vascular puncture is a commonly used examination and treatment method in clinical practice, and the most common one is venous puncture. The operation process mainly includes: 1. Penetrating the puncture needle through the skin and blood vessel wall into the blood vessel; 2. Fixing the puncture needle on the skin surface; 3. Injecting drugs or collecting blood; 4. Pulling out the puncture needle and compressing to stop bleeding. Most of the puncture needles commonly used in clinical practice are directly fixed on the skin surface with adhesive tape. During the operation, medical staff first insert the puncture needle into the blood vessel, and then change hands to hold the adhesive tape to fix the tail of the puncture needle on the skin surface. The risks of this operation are as follows: 1. During the process of sticking the adhesive tape, the puncture needle will be touched, causing the needle tip to move in the blood vessel, scratching the vascular endothelium, or even accidentally injuring, piercing the blood vessel wall, or the needle slipping out of the blood vessel; 2. It is difficult to fix firmly and is prone to sliding; 3. When pulling out the needle, the adhesive tape needs to be removed first, and during the process of removing the adhesive tape, the puncture needle will be continuously touched, and the accidental movement of the needle tip in the blood vessel is likely to damage the inner wall of the blood vessel, or even accidentally injure and pierce the blood vessel wall; 4. When withdrawing the needle, we hope that the puncture needle can accurately withdraw along the axis direction of the needle tip, but it is very difficult to achieve this in actual operation, and often the needle tip will scratch the inner wall of the blood vessel.

[0003] During the puncture operation, we hope that the puncture needle is convenient to operate and can be quickly fixed on the skin surface; during the injection of drugs or blood collection after successful puncture, we hope that the puncture needle has good stability, is firmly fixed, and is not prone to accidental sliding; at the end of the treatment, we need the puncture needle to be pulled out conveniently and safely to reduce the damage to the blood vessel. Therefore, at present, we need a puncture needle fixing device that can firmly fix the needle tip and can pull out the puncture needle safely and quickly when pulling out the needle.

[0021] The present disclosure describes a puncture needle fixing bracket, which mainly includes parts such as a bracket body part, a left bracket wing, a right bracket wing, a pin lock, etc.

[0022] Each aspect may include one or more of the following features. The bracket body part has a longitudinal groove that can accommodate the body part of the puncture needle. The cross-section of the bracket body part is in a "C" shape or other shapes, and may also have different cross-sectional shapes in different segments. The bracket body part is made of an elastic material and can be bent and deformed. The left bracket wing is connected to the left side of the bracket body part. A puncture needle fixing pin lock is attached to the rear of the left bracket wing. A snap structure is attached to the outside of the left bracket wing. The right bracket wing is connected to the right side of the bracket body part, and a pasting film and a release film are attached to the lower surface of the right bracket wing. A snap structure is provided on the outside of the right bracket wing and can be coupled with the snap structure of the left bracket wing. The front edges and outer edges of the left bracket wing and the right bracket wing bulge upward and the thickness increases. The left bracket wing can be flipped towards the right bracket wing, the bracket body part is further bent and deformed, and the snap structure of the left bracket wing is coupled with the snap structure of the right bracket wing. At this time, a cavity is formed between the left bracket wing and the right bracket wing, which can accommodate the shank of the puncture needle.

[0023] Each aspect may also include one or more of the following features. A fixing pin lock is attached to the rear of the lower surface of the left bracket wing. The rear end of the fixing pin lock is fixed to the lower surface of the left bracket wing. The body part of the fixing pin lock can undergo elastic deformation and maintain an elastic force forward and towards the left bracket wing. There is a protruding pin lock bolt at the front of the fixing pin lock. Pin lock holes are provided at the positions corresponding to the pin lock bolt on both the left bracket wing and the right bracket wing.

The medical staff holds the closed left and right wings of the stent and inserts the front part of the metal needle tip of the puncture needle into the blood vessel, tears off the isolation film, and the adhesive film adheres to the skin surface. Then fix the stent together with the puncture needle on the skin surface. According to specific needs, auxiliary fixing adhesive tapes can also be pasted on the surface of the stent to fix the stent more firmly on the skin surface. At the end of the treatment, gently lift the front part of the fixing pin lock, the lock bolt exits the right wing lock hole and the left wing lock hole to release the lock, and the puncture needle tip can smoothly exit along its axis direction. Immediately press the puncture point to stop bleeding, and then remove the adhesive tape and the stent after sufficient hemostasis.

[0039] Please refer to Figures 1 to 6 . In an embodiment of the present application, a puncture needle fixing bracket 001 is provided. Among them, the puncture needle 012 has a puncture needle body portion 007, a needle handle 014, and a metal needle tip 022. The puncture needle fixing bracket 001 includes: a bracket body portion 002 provided with a receiving groove 006 for receiving the puncture needle body portion 007; a first wing portion 003 disposed on one side of the receiving groove 006; and a second wing portion 004 disposed on the other side of the receiving groove 006. The first wing portion 003 and the second wing portion 004 are distributed on both sides of the receiving groove 006.

[0040] The accommodating groove 006 penetrates the bracket body portion 002 along the length direction; the accommodating groove 006 forms an accommodating opening on one surface of the bracket body portion 002. The first wing portion 003 is provided with a first engaging portion 008. The second wing portion 004 is provided with a second engaging portion 009 that engages with the first engaging portion 008; the second wing portion 004 and the first wing portion 003 can be turned over and closed around the bracket body portion 002, and the first engaging portion 008 and the second engaging portion 009 engage to maintain the closed state of the first wing portion 003 and the second wing portion 004. When the first wing portion 003 and the second wing portion 004 are closed, a wing cavity 013 for accommodating the needle handle 014 is formed, and the wing cavity 013 communicates with the accommodating groove 006. The shape of the wing cavity 013 can match the shape of the needle handle 014.

[0041] The puncture needle fixing bracket 001 provided in this embodiment can clamp and fix the puncture needle 012 after the first wing portion 003 and the second wing portion 004 are closed, so that the puncture needle 012 can be firmly fixed by fixing the puncture needle fixing bracket 001 at a target position (such as the back of the hand). And when it is necessary to pull out the puncture needle 012, only the puncture needle 012 needs to be withdrawn from the puncture needle fixing bracket 001 along its own axis direction, and the puncture needle fixing bracket 001 can assist the puncture needle 012 to be smoothly taken out due to its own fixed state.

[0042] In this embodiment, the puncture needle fixing bracket 001 has an open state (such as Figure 1 ) and a closed state (such as Figure 3 ). The puncture needle fixing bracket 001 switches between the open state and the closed state by the flipping of the first wing portion 003 and the second wing portion 004, or can only switch from the open state to the closed state. In the open state, the puncture needle body portion 007 can be placed into the accommodating groove 006 from above through the opening of the accommodating groove 006.

[0043] The first engaging portion 008 and the second engaging portion 009 are of separable connection or detachable connection. Among them, the first engaging portion 008 and the second engaging portion 009 can be a plug-in structure or a snap structure. In this embodiment, the first engaging portion 008 and the second engaging portion 009 form a snap structure.

[0044] In this embodiment, the first wing portion 003 and the second wing portion 004 are respectively located on both sides of the bracket body portion 002 (accommodating groove 006) in the open state. During the flipping process, the bracket body portion 002 may deform or may not deform (for example, the first wing portion 003 and the second wing portion 004 are sleeved on the bracket body portion 002). In this embodiment, the bracket body portion 002 is made of a flexible material, such as a flexible plastic material or a rubber material. Preferably, the bracket body portion 002 is made of a transparent flexible plastic material. The first wing portion 003, the second wing portion 004 and the bracket body portion 002 are of an integral structure. The first wing portion 003 and the second wing portion 004 may be made of a rigid plastic material relative to the bracket body portion 002 and are not easily deformed during the flipping process.

[0045] To facilitate the accommodation of the needle handle 014, at least one of the first wing portion 003 and the second wing portion 004 is provided with a recessed portion 050. When the first wing portion 003 and the second wing portion 004 are covered, the recessed portion 050 forms the wing cavity 013. In this embodiment, both the first wing portion 003 and the second wing portion 004 are provided with recessed portions 050. When covered, the recessed portion 050 of the first wing portion 003 and the recessed portion 050 of the second wing portion 004 face each other to form the wing cavity 013.

[0046] The first wing portion 003 and / or the second wing portion 004 has a first side wall 052 and a second side wall along the length direction of the accommodation groove 006. An inlet / outlet 051 communicating with the wing cavity 013 is formed on the first side wall 052 of the first wing portion 003 and / or the second wing portion 004, and the second side wall has a blocking structure 055 for limiting the needle handle 014.

[0047] Taking the puncture direction of the puncture needle 012 as the front-rear direction, the front side wall (second side wall) of the first wing portion 003 and / or the second wing portion 004 is provided with a blocking structure 055, and the rear side wall (first side wall 052) is provided with an inlet / outlet 051 communicating with the accommodation groove 006. In this embodiment, the leading edges (front side walls) of the first wing portion 003 and the second wing portion 004 bulge upward and the thickness increases to form the blocking structure 055. By providing the blocking structure 055, only the puncture needle 012 is allowed to move out backward. In the open state, the puncture needle 012 can be placed on the fixing bracket 001.

[0048] The first wing portion 003 is also provided with a locking assembly. The locking assembly and the blocking structure 055 cooperate to limit the needle handle 014 between the locking assembly and the blocking structure 055. Specifically, the locking assembly includes a pin lock 005; one end of the pin lock 005 is fixedly attached to the surface of the first wing portion 003 facing away from the second wing portion 004, and a pin lock bolt 016 is provided at the front end 019 of the pin lock 005; a first pin lock hole 017 is provided on the first wing portion 003, and a second pin lock hole 018 opposite to the first pin lock hole 017 is provided on the second wing portion 004.

[0049] The locking assembly has a locked state ( Figure 3 ), and an unlocked state ( Figure 4 ). When the locking assembly is in the locked state, the pin lock bolt 016 passes through the first pin lock hole 017 and the wing cavity 013 and inserts into the second pin lock hole 018; when the locking assembly is in the unlocked state, the pin lock bolt 016 is removed from the second pin lock hole 018 and the wing cavity 013.

[0050] When the user needs to unlock the pin lock 005, the pin lock 005 can be directly damaged, or the front end 019 of the pin lock 005 of the pin lock 005 can be lifted upward so that the pin lock bolt 016 is removed from the first pin lock hole 017 and can be reset when necessary. In this embodiment, for repeated use and to maintain the limitation of the needle handle 014, the pin lock 005 is an elastic structure and maintains an elastic force forward and toward the second wing portion 004. The pin lock 005 and the pin lock bolt 016 can be an integral structure, and the pin lock 005 can be made of rubber material and is integrally strip-shaped, and one end of it is fixed to the back surface of the first wing portion 003. Specifically, this end can be pasted on the back surface of the first wing portion 003.

[0051] To facilitate the fixing of the fixing bracket 001 on the surface of the target object, the surface of the second wing portion 004 facing away from the first wing portion 003 is provided with a pasting portion 010. The pasting portion 010 is provided on the back surface of the second wing portion 004, and the pasting portion 010 has a pasting surface for pasting at the target position. The pasting surface can be the lower surface of the pasting portion 010. The accommodating groove 006 and the wing cavity 013 have a running direction obliquely downward from back to front relative to the pasting surface. Preferably, the included angle between the length direction of the accommodating groove 006 and the pasting surface can be between 1 degree and 40 degrees.

[0052] To fix the fixing bracket 001 on the patient's skin, the pasting portion 010 includes a pasting film, and the pasting surface is covered with a removable release film 011. In this embodiment, the cross-section of a part of the second wing portion 004 can be a conical structure, forming an inclined wing cavity 013.

[0053] For the convenience of understanding the present application, an embodiment of the present application will be described in detail below with reference to the accompanying drawings. During the following description process, for further convenience of understanding this embodiment, the left and right orientations when facing Figure 1 are used to name the first wing portion 003 and the second wing portion 004 as "left bracket wing" and "right bracket wing"; correspondingly, the first joint portion 008 and the second joint portion 009 respectively adopt the "left buckle structure", "right buckle structure", etc. in their specific embodiments.

[0054] Figure 1 、 Figure 2 Fig. shows the fixing bracket 001. The fixing bracket 001 mainly consists of a bracket body portion 002, a left bracket wing 003 (an embodiment of the first wing portion), a right bracket wing 004 (an embodiment of the second wing portion), a pin lock 005, and other parts. There is a longitudinal groove 006 (an embodiment of the receiving groove) in the bracket body portion 002, and the groove 006 can accommodate the puncture needle body portion 007. The cross-section of the bracket body portion 002 is in a "C" shape or other shapes, and can also have different cross-sectional shapes in different segments. The bracket body portion 002 is made of a material with elasticity that can undergo bending deformation. The left bracket wing 003 is connected to the left side of the bracket body portion 002. There is a pin lock 005 at the rear of the left bracket wing 003 to prevent the needle handle 014 from retreating. There is a left buckle structure 008 on the outer side of the left bracket wing 003. The left buckle structure 008 is located outside the recessed portion 050 of the left bracket wing 003. There is a right buckle structure 009 on the outer side of the right bracket wing 004. The right buckle structure 009 is located outside the recessed portion 050 of the right bracket wing 004. The left buckle structure 008 can be coupled with the right buckle structure 009, so that the left bracket wing 003 and the right bracket wing 004 are tightly fixed to each other. The right bracket wing 004 is connected to the right side of the bracket body portion 002. A sticking film 010 is attached to the back of the right bracket wing 004. An isolation film 011 is attached to the lower surface of the sticking film 010. The front edges and outer edges of the left bracket wing 003 and the right bracket wing 004 bulge upward and the thickness increases. There is a left wing pin lock hole 017 (an embodiment of the first pin lock hole) at the rear of the left bracket wing 003. There is a right wing pin lock hole 018 (an embodiment of the second pin lock hole) at the rear of the right bracket wing 004.

[0055] Figure 3 、 Figure 4 、 Figure 5 and Figure 6 Fig. shows the fixing bracket 001 when the puncture needle 012 is loaded. The left bracket wing 003 can utilize the bending deformation of the bracket body portion 002 to flip towards the right bracket wing 004, and is tightly fixed to the right bracket wing 004 by the mutual coupling action of the left buckle structure 008 and the right buckle structure 009. At this time, a wing cavity 013 is formed between the left bracket wing 003 and the right bracket wing 004, which can accommodate the needle handle 014 of the puncture needle 012.

[0056] A pin lock 005 is attached to the rear of the left wing 003 of the bracket. The pin lock rear end 015 of the pin lock 005 is attached and fixed to the rear of the lower surface of the left wing 003 of the bracket. A pin lock bolt 016 is provided at the front of the pin lock 005. The body of the pin lock 005 is made of elastic material, which can be elastically deformed and maintain an elastic force that is close to the front and the left wing 003 of the bracket, so as to change the locked and unlocked states. When locking, the pin lock bolt 016 passes through the left wing pin lock hole 017 to reach the right wing pin lock hole 018, preventing the needle handle 014 from retreating; when unlocking, it is only necessary to lift the front end 019 of the pin lock to pull the pin lock bolt 016 out of the left wing pin lock hole 017. After releasing your hand, under the action of the oblique elastic force of the pin lock 005 itself, the front end 019 of the pin lock moves forward and staggers the position of the left wing pin lock hole 017. The pin lock bolt 016 will not automatically insert into the left wing pin lock hole 017 again, avoiding the occurrence of accidental locking and being able to maintain the unlocked state. At this time, the puncture needle 012 can be smoothly withdrawn along the axis direction of the needle tip.

[0057] The groove 006 and the wing cavity 013 run obliquely downward from back to front (with the lower surface of the right wing 004 of the stent as the horizontal reference plane), so that the axis of the puncture needle 012 forms a certain angle 021 with the plane of the skin 020.

[0058] During use, the puncture needle body 007 is placed in the groove 006 of the fixed bracket 001, the bracket left wing 003 is turned over and pressed against the bracket right wing 004, the left buckle structure 008 and the right buckle structure 009 are coupled and fixed to each other, at this time, the pin lock 005 at the rear of the bracket left wing 003 is in a locked state, and the puncture needle body 007 and the needle handle 014 are firmly clamped between the bracket left wing 003 and the bracket right wing 004. The medical staff holds the bracket left wing 003 and the bracket right wing 004 closed together, inserts the front part of the metal needle 022 into the blood vessel (not shown), tears off the isolation film 011, and the adhesive film 010 is adhered to the surface of the skin 020, and the fixed bracket 001 is fixed to the surface of the skin 020 together with the puncture needle 012. According to the specific situation, a large-area auxiliary fixing tape (not shown) can also be pasted on the surface of the fixed bracket 001 to fix the fixed bracket 001 more firmly on the surface of the skin 020. At the end of the treatment, the pin lock front end 019 is gently lifted, the pin lock bolt 016 is pulled out, the lock is released, and the puncture needle 012 can be smoothly withdrawn along its axis direction. The puncture point is immediately compressed to stop bleeding, and the adhesive tape and the fixing bracket 001 are removed after sufficient bleeding stops.
