Referring to fig. 1-3, the present application provides a tissue fastening assembly 10 including a housing 100, a fastening member 200, and a spray head 300. The housing 100 is substantially U-shaped, the fixing member 200 may be a suction cup embedded in the housing 100, and the housing 100 may be fixed to the target tissue by the fixing member 200. The target tissue may be a myocardial tissue. The spray head 300 is rotatably connected with the housing 100 and at least a part of the structure is exposed outside the housing 100. A rotational damping force can be generated between the spray head 300 and the housing 100 to fix the relative position of the spray head 300 and the housing 100, and the rotational damping force can be considered to limit the relative movement of the spray head 300 and the housing 100. Spray head 300 is configured to rotate relative to housing 100 against a rotational damping force under an external force, and spray head 300 is used to spray cleaning material to a target tissue. Wherein the cleaning material can be liquid with cleaning effect such as purified water and normal saline, or gas such as carbon dioxide and nitrogen.

When the tissue fastening assembly 10 is used, a user (such as an operator) can fix the tissue fastening assembly 10 on a target tissue by using the fixing member 200 of the housing 100. The spray head 300 can spray cleaning material to wash target tissue to prevent foreign objects from interfering with the user's sight. During a surgical procedure, a user may manipulate sprayhead 300 to rotate relative to housing 100. For example, the user can use surgical tools such as tweezers to stir the nozzle 300 to rotate, that is, the user can flexibly adjust the spraying angle of the nozzle 300 according to actual needs, so as to clean the foreign matter attached to the target component. It should be emphasized that after the user adjusts the position of spray head 300, since there is a rotational damping force between spray head 300 and housing 100, the rotational damping force can keep the relative position of spray head 300 and housing 100 stable, i.e. the spraying angle of spray head 300 is fixed, in the case that spray head 300 is not subjected to an external force. In other words, after the user adjusts the nozzle 300, the nozzle 300 can automatically maintain the current spraying angle to flush a certain portion of the target tissue, so that the cleaning effect is better and the user operation is more convenient.

Referring to fig. 2, in some embodiments, the spray head 300 includes a rotating portion 310 and a water spraying portion 320 connected to the rotating portion 310. The water spray part 320 is penetrated through the housing 100 and exposed outside the housing 100, and the water spray part 320 is used to spray the detergent to the target tissue. The rotating portion 310 is rotatably connected in the housing 100, and the rotating portion 310 and the inner wall of the housing 100 are pressed against each other to generate a rotational damping force to fix the relative position of the water spraying portion 320 and the housing 100, and the water spraying portion 320 is configured to overcome the rotational damping force and drive the rotating portion 310 to rotate relative to the housing 100 under the action of an external force.

Specifically, in the embodiment shown in fig. 2, the tissue fixing assembly 10 further includes an elastic member 400 disposed in the housing 100, and the elastic member 400 may be a compression spring. The housing 100 includes a base 110 and an upper cover 120, the upper cover 120 covers the base 110, and the upper cover 120 and the base 110 enclose to form a rotation slot 130. The rotating portion 310 is rotatably disposed in the rotating groove 130, one end of the elastic member 400 abuts against the casing 100, and the other end of the elastic member 400 abuts against the rotating portion 310, so that the rotating portion 310 and the groove wall of the rotating groove 130 are pressed against each other to generate a rotational damping force. It should be noted that, since the rotation slot 130 is formed by the structure of the casing 100, one end of the elastic element 400 abuts against the casing 100, and it may be considered that one end of the elastic element 400 abuts against the inner wall of the casing 100 and is located outside the rotation slot 130, or it may be considered that one end of the elastic element 400 directly abuts against the inner wall of the rotation slot 130. The user can change the interaction force between the spray head 300 and the housing 100 by changing the pressure applied to the spray head 300 by the elastic member 400, thereby changing the magnitude of the rotational damping force.

Alternatively, the base 110 and the cover 120 may be detachably connected by bonding, snapping, screwing, welding, or the like, or may be integrally formed.

Preferably, in some embodiments, the rotating portion 310 is spherical, and the rotating groove 130 is adapted to the rotating portion 310 in shape and size, i.e., the rotating groove 130 is a spherical groove. The universal ball-like structure allows the angle of the nozzle 300 to be adjusted more flexibly.

More specifically, as shown in fig. 2, in some embodiments, the tissue fixation assembly 10 further includes an injection tubule 500 disposed through the housing 100. The water outlet 321 is opened at one end of the water spraying part 320 far away from the rotating part 310, the water inlet 311 is opened on the rotating part 310, and the water inlet 311 is communicated with the water outlet 321. One end of the injection tubule 500 is connected to the water inlet 311, and the other end is used for connecting the injection tube 40, i.e. the water inlet 311 is communicated with the injection tube 40 through the injection tubule 500. Further, in some embodiments, injection tube 40 may be further connected to a delivery pump, which is located remotely from injection tubing 500, and which is capable of delivering the same into injection tubing 500 along injection tube 40 and ultimately out of water-jet section 320 of spray head 300.

In some embodiments, a damping coating may be applied to the surface of the rotation slot 130 and/or the rotation portion 310 to promote the effective generation of the rotation damping force between the rotation portion 310 and the slot wall of the rotation slot 130.

Referring to fig. 1, the present application further relates to a heart stabilizer including a base 30, a movable arm 20, and a tissue fixation assembly 10 according to any of the above embodiments. Base 30 is adapted to be secured to a chest retractor, and one end of moveable arm 20 is coupled to base 30, and the other end of moveable arm 20 is adapted to be coupled to housing 100 to move tissue fixation assembly 10 relative to cardiac tissue. Wherein, the movable arm 20 can be a universal flexible arm, and the user can operate the movable arm 20 to twist and deform to drive the whole tissue fixing assembly 10 to move relative to the target tissue, and then fix the whole tissue fixing assembly 10 on the target tissue by using the fixing element 200 on the housing 100. In the operation process, the user can operate the nozzle 300 to rotate relative to the housing 100, that is, the user can flexibly adjust the spraying angle of the nozzle 300 according to the actual requirement, so as to clean the foreign matters attached to the target component and prevent the foreign matters from interfering with the sight of the user. The rotational damping force can stabilize the relative position of spray head 300 and housing 100, i.e., spray head 300 can automatically maintain the current spray angle to flush the target tissue.

As shown in fig. 1, in some embodiments, the heart stabilizer further comprises a syringe 40 and a first control valve 61 for controlling the on-off of the syringe 40. The first control valve 61 is fixed to the base 30, and the injection tube 40 communicates with the spray head 300 and serves to deliver the cleaning agent to the spray head 300. Optionally, the first control valve 61 and the base 30 may be fixedly connected by bonding, welding, or the like, or detachably connected by screwing, clipping, or interference fit, or the like.

The syringe 40 may have a plurality of tube segments, among others. For example, in the embodiment shown in fig. 1, the injection tube 40 includes a first injection tube 41 and a second injection tube 42, and the first control valve 61 is a two-way valve. First syringe 41 is connected between first control valve 61 and the suction cup of tissue fixation assembly 10. The second injection pipe 42 is connected to the other end of the first control valve 61, and the end of the second injection pipe 42 remote from the first control valve 61 is connected to a three-way valve 70. The first control valve 61 is provided to control the delivery of the cleaning agent in the syringe 40, and to fix the syringe 40 on the base 30, so as to prevent the syringe 40 from being placed in a mess during the operation and interfering with the normal operation. In practical applications, the length of second syringe 42 may be much longer than that shown in fig. 1, so that first control valve 61 can effectively restrain syringe 40 and prevent syringe 40 from affecting the field of view of the operator due to the absence of restraint. In addition, the first control valve 61 is directly disposed on the base 30, so that the user does not need to search for the valve body along the length of the syringe tube 40, which is more convenient for the user to operate.

With continued reference to fig. 1, in some embodiments, the heart stabilizer further includes a negative pressure tube 50 and a second control valve 62 controlling the negative pressure tube 50, the second control valve 62 being secured to the base 30. Taking the fixing member 200 as a suction cup as an example, an independent air pressure channel may be formed in the housing 100, the negative pressure tube 50 is communicated with the fixing member 200 through the air pressure channel, the negative pressure tube 50 is communicated with the fixing member 200, and the fixing member 200 is used for being adsorbed onto a target tissue. Alternatively, the second control valve 62 may be fixedly connected to the base 30 by bonding, welding, or the like, or detachably connected by screwing, clipping, or interference fit, or the like.

The negative pressure pipe 50 may have a plurality of pipe sections. For example, in the embodiment shown in fig. 1, the negative pressure pipe 50 includes a first negative pressure pipe 51 and a second negative pressure pipe 52, and the second control valve 62 is a two-way valve. The first negative pressure pipe 51 is connected between the second control valve 62 and the water inlet of the spray head 300. The second negative pressure pipe 52 is connected to the other end of the second control valve 62, and the end of the second negative pressure pipe 52 remote from the second control valve 62 is connected to a three-way valve 70. In practical application scenarios, the length of the second negative pressure tube 52 may be much longer than that shown in fig. 1, so that the second control valve 62 can effectively restrain the negative pressure tube 50, and prevent the visual field of the operator from being affected by the negative pressure tube 50 due to no restraint. In addition, the second control valve 62 is directly arranged on the base 30, so that a user does not need to search for the valve body along the length extension direction of the negative pressure pipe 50, and the operation of the user is facilitated.
