1. Field of the Invention
The present invention relates to a medical instrument holding apparatus, and more particularly to a medical instrument holding apparatus including an improved or simplified structure or configuration that may be easily and quickly made or manufactured by the manufacturers and that may be easily used to conduct the operation on the patient, and that may be used or provided for easily and quickly and effectively indicating or locating the remote of center motion (RCM) or index mark in the animal or human body or the other objects and for allowing the medical surgery or medical operation to be easily conducted or actuated by the users or operators.
2. Description of the Prior Art
Typical medical instruments, such as rigidoscopes, laparoscopes, endoscopes, trocars, treating instruments, or the other medical instruments or the like have been developed and widely provided and used for conducting or operating an operation on a patient, and are typically grasped and held by the hands of the operators, such as the doctors, and it will be difficult for the operators or the doctors to hold the medical instruments and to conduct or operate the operation on the patient.
Normally, the medical instruments are grasped and held by one of the operators or the doctors, and the other operator or doctor will stand beside the medical instruments holding operator and will both standing near the patient at the same time, in a tiny or narrowed operation room.
For allowing the medical instruments to be held in place without being grasped by the operators or the doctors, a scope-holder has been disclosed and used to hold the medical instruments in place, for inserting the medical instruments into the abdominal cavity of a patient.
For example, U.S. Pat. No. 5,697,939 to Kubota et al. discloses one of the typical medical instrument holding apparatuses comprising a plurality of arms sections and holding sections for holding and grasping the treating instrument or medical instrument and for engaging or inserting the treating or medical instruments into the abdominal cavity of the patient.
However, the typical medical instrument holding apparatuses comprise a rather complicated structure or configuration having a number of parts or elements that may not be easily and quickly made or manufactured and that may not be easily used to conduct the operation on the patient.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional medical instrument holding apparatuses.
The primary objective of the present invention is to provide a medical instrument holding apparatus including an improved or simplified structure or configuration that may be easily and quickly made or manufactured by the manufacturers and that may be easily used to conduct the operation on the patient.
The other objective of the present invention is to provide a medical instrument holding apparatus including an improved or simplified structure or configuration that may be used or provided for easily and quickly and effectively indicating or locating the remote of center motion (RCM) or index mark in the animal or human body or the other objects and for allowing the medical surgery or medical operation to be easily conducted or actuated by the users or operators.
In accordance with one aspect of the invention, there is provided a medical instrument holding apparatus comprising a longitudinal shaft, an attachment device attached to the longitudinal shaft, the attachment device including a casing, a coupling device attached to the casing of the attachment device, a carrying device attached to the coupling device, and the carrying device including an orifice and an aperture formed therein, the aperture of the carrying device being tilted and inclined relative to the orifice of the carrying device, a medical instrument including an insertion tube extended therefrom and engaged into the orifice of the carrying device, and a projecting device engaged in the aperture of the carrying device for projecting a light onto the insertion tube of the medical instrument and for intersecting or contacting or engaging with the insertion tube of the medical instrument at a remote of center motion (RCM) or index mark, and the medical instrument holding apparatus includes an improved or simplified structure or configuration that may be easily and quickly made or manufactured by the manufacturers and that may be easily used to conduct the operation on the patient.
The aperture of the carrying device is tilted and inclined relative to the orifice of the carrying device for an included angle (a), for allowing the light projected by the projecting device to be intersected or contacted or engaged with the insertion tube of the medical instrument at a remote of center motion (RCM) or index mark.
The carrying device includes a middle portion having a groove for defining a spring blade in the middle portion of the carrying device, and arranged for allowing the orifice of the carrying device to be formed between the spring blade and the middle portion of the carrying device and for allowing the insertion tube of the medical instrument to be retained between the spring blade and the middle portion of the carrying device.
The carrying device includes a fastener engaged onto the middle portion of the carrying device and engaged through the groove of the carrying device and engaged with the spring blade for forcing the spring blade to move toward the middle portion of the carrying device and to secure the insertion tube of the medical instrument to the carrying device.
The carrying device includes a bracket having an engaging slot, such as a dove-tail slot formed therein, and the coupling device includes one or more, such as two spring biased catches engaged with the engaging slot of the bracket for detachably securing the carrying device to the coupling device.
The carrying device includes a narrowed neck segment extended therefrom, the spring biased catches are extended from the neck segment and include an outer diameter or outer dimension smaller than that of the neck segment of the coupling device for forming a peripheral shoulder between the spring biased catch and the neck segment and for engaging with the bracket of the carrying device.
The attachment device includes an engaging slot, such as a dove-tail slot formed in the casing, and the coupling device includes one or more, such as two spring biased arms extended outwardly therefrom and engaged with the engaging slot of the attachment device for detachably securing the coupling device to the attachment device.
Further objectives and advantages of the present invention will become apparent from a careful reading of the detailed description provided hereinbelow, with appropriate reference to the accompanying drawings.
Referring to the drawings, and initially to
